In Triangle ABC what is the value of Tan A by 2 in terms of its sides if angle B is 90 degrees?

If B is 90 degrees, Tan A is BC / AB. But I don't know what you mean by Tan A by 2.

Can a triangle be both isosceles and obtuse?
these are two different terms, isosceles means a triangle with two sides the same length, and hence two angles the same length. obtuse means there is at least one angle that is greater than 90 degrees. since two of the angle have to be the same, you know that only one such angle can exist, so is with any triangle anyway. just try to imagine a triangle with two sides the same length with one angle larger than 90 degrees. yup it's possible
What terms can be used to describe a triangle whose angle measures are 30 120 and 30 degrees?
Acute
What two terms could be used to describe a triangle with all sides the same length and all angles measuring 60 degrees?
Equilateral and acute
What is a vertical angle in math terms?
It is a right angle (a 900 angle).
What is a triangle with three different sides called?
In terms of the length the sides of a triangle it can be classified into three types:if all three sides are equal then the triangle is an equilateral triangleif only two sides are equal then the triangle is an isosceles triangleif none of the three sides are equal then the triangle is called a scalene triangle

Is an scalene triangle an obtuse or an right triangle?
A scalene has three sides of unequal lengths, and all threes angles different.The largest angle defines the triangle¹:acute: a scalene triangle could have sides 6, 9, 10right angle: a scalene triangle could have sides 6, 8, 10obtuse: a scalene triangle could have sides 6, 7, 10So a scalene triangle could be any of acute, right angle or obtuse.¹In terms of acute, right angle or obtuse. Triangles can also be defined in terms of their sides: equilateral (all three sides equal), isosceles (two sides equals) or scalene (no sides equal)
What terms can be used to describe a triangle whose angle measures are 30 120 and 30 degrees?
Acute
What is the measure of the largest angle in an obtuse triangle?
178 degrees is the largest angle for an obtuse angle because 180 is a straight angle and 90 degrees is an right angle and below 90 degrees is an acute angle. Some supposedly say that the answer is 179,But it's not! the reason behind this is because in a triangle all the angles have to add up to 180 degrees. There are 3 points to a triangle so there has to be 2 extra degrees taken off of 180, which equals to 178. Explanation is terms: angle A + angle B + angle C = 180 degrees [Sum of supplementary angles of a triangle] 178 degrees + 1 degree + 1 degree = 180 degrees which makes sense. I figured this out when i was doing homework... Hope this helps you other people
Does a triangle have to have a 90 degree angle?
Unless it is a religious triangle it does not have to have any angels! Seriously, though, a triangle does not have to have a 90 degree angle. In terms of its angles, the only requirement is that the measures of the three angles adds to 180 degrees (or pi radians).
BC is one side of a regular n-gon the sides next to BC are extended to meet at W Find the measure of angle W in terms of n?
The question is not very coherent. However if the sides either side of BC are able to meet at a point, then the angle between BC and the adjacent sides must be less than 90 degrees. Hence the shape can only be a triangle and since it's regular the angle must be 60 degrees. So if n is 3, the angle (60) is 20n.
How is the degrees of a triangle calculated?
there is 180 degrees in a triangle (a triangle is 1/2 a sguare which is 360 degrees). To find the area of a triangle, use the formula a=base x heighth /2. (bh/2) example: angles given: x, 2x, 55. combine like terms: 3x+55=180 subtract 55 from both sides: 3x=125 divide both sides by 3: x=41.67 the angle measurements are: x=41.67, 2x=83.33, 55 check answer by plugging in x: 41.67+83.33+55=180
How many sides does a hexagonal triangle have?
Although "hexagonal triangle" is a contradiction in terms, a triangle always has three sides and a hexagon always has six.
What two terms could be used to describe a triangle with all sides the same length and all angles measuring 60 degrees?
Equilateral and acute
What is a vertical angle in math terms?
It is a right angle (a 900 angle).
What is a triangle with three different sides called?
In terms of the length the sides of a triangle it can be classified into three types:if all three sides are equal then the triangle is an equilateral triangleif only two sides are equal then the triangle is an isosceles triangleif none of the three sides are equal then the triangle is called a scalene triangle
Different types of triangles can be created by combining 2 what terms scalene isosceles equilateral acute obtuse and right. What combination of these terms will not form triangles?
An equilateral triangle has to be acute. All the sides are the same size, and all the angles are the same size. You can't have three 90 degree angles in a triangle or three angles that are more than 90 degrees in a triangle. Therefore the angles have to be acute. An isosceles triangle will have two angles at are the same size. You can't have two 90 degree angles or two angles over 90 degrees in a triangle, but the triangle only has to have one of those angles to be either right or obtuse. The right or obtuse angle must be between the two sides that are equal and the two angles that are equal have to be acute. So then an isosceles triangle can be any of the three - acute, obtuse, or right. A scalene triangle has three unequal sides. Therefore, the angles will all be unequal. Can you think of any three angles that are all less than 90 degrees that will add up to 180 degrees? (acute?) What about any two angles (not equal) that will add to another 90 degree angle to make 180 degrees? (right?) What about any two angles (not equal) that will add to another angle larger than 90 degree to make 180 degrees? (obtuse?) Therefore there are 7 possible combinations.
