The answer is 31.6874, however I cannot explain the math used to get that answer..... I just drew the lines and angle on a cad system and measured the third line.
In an isosceles triangle there are two equal sides and two equal angles. In a triangle ABC, if angle A is between the sides of equal length, then angles B and C are equal.Without knowing which angle (A, B or C above) is 66o there are two possible answers:If the 66o angle is between the two sides of equal length (angle A) then the other two angles (B and C) are (180o - 66o) / 2 = 57o each.If the 66o angle is not between the sides of equal length (angle B or C), then the other two angles are 66o (the other angle of C and B) and (angle A) 180o - 66o x 2 = 48o.
If it's a right angle triangle then:- a2+b2 = c2 where 'c' is the hypotenuse and the square root of this is the length of the hypotenuse when 'a' and 'b' are the other sides of the right angle triangle.
Like a 3 sided triangle each side being of equal length -- correction -- That's a 60 degree angle!. A 45 degree angle is formed in a right-angle triangle when the other two sides are of equal length. --correction-- learn your maths!?! .....................that was mean sorry
This is the description of the Pythagorean theorem. It applies to any "right" triangle -- that is, a triangle with one angle of exactly 90-degrees, and two other angles that add up to 90-degrees. A = the measurement of the length of one side of the triangle making up the 90-degree angle. B = the measurement of the length of the OTHER side of the triangle making up the 90-degree angle, perpendicular to "A". C = the measurement of the length of the third side of the triangle opposite to the 90-degree angle, also called the hypotenuse In any right triangle, A-squared + B-squared = C-squared
A hypotenuse is the longest side of a right angled triangle. The length of a hypotenuse can be found using the Pythagorean Theorem. This states that in a right angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. This means that to find the length of the hypotenuse, you need to know the lengths of the other two sides.
Using the cosine rule: 13.0112367 cm The triangle is in fact an isosceles triangle.
-- Like every triangle, a right triangle has three interior angles.-- Unlike any other triangle, one of the angles in a right triangle is a right angle.The other two are both acute angles.-- One acute angle is the angle whose cosine is length of one leg / length of hypotenuse-- Other acute angle is the angle whose sine is length of the same leg / length of the hypotenuse-- The length of the hypotenuse is the square root of [ (length of one leg)2 + length of other leg)2 ]
I don't think it is possible. You would have to know at least one other measurement such as the angle between the length and width or the length of one of the sides.
In a right triangle, the tangent of an angle other than the right angle is the ratio of the length of the side opposite the angle over the length of the side adjacent to the angle (the side between the angle and the right angle).
In an isosceles triangle there are two equal sides and two equal angles. In a triangle ABC, if angle A is between the sides of equal length, then angles B and C are equal.Without knowing which angle (A, B or C above) is 66o there are two possible answers:If the 66o angle is between the two sides of equal length (angle A) then the other two angles (B and C) are (180o - 66o) / 2 = 57o each.If the 66o angle is not between the sides of equal length (angle B or C), then the other two angles are 66o (the other angle of C and B) and (angle A) 180o - 66o x 2 = 48o.
The answer may refer to a triangle for which the length of two sides and the measure of an angle - other than the included angle - are known.
A right-angled triangle can be an Isosceles Triangle, but NOT an equilateral triangle. An Isosceles triangle has two sides of equal length. They form the 90 degree (right angle). The hypotenuse is opposite the right angle, and is longer than the other two sides.
17 cm because it's an equilateral triangle
The Pythagorean Theorem explains (or permits calculation of) the length of one side of a right triangle if the lengths of the other two sides are known. A right triangle is a triangle in which one of the three angles is a right angle (i.e. it has 90 degrees) For that kind of triangle, if A = the length of one of the sides making the right angle, B = the length of the other side making the right triangle, and C = the length of the side opposite to the right angle (also called the hypotenuse, then C2 = A2 + B2
An OBTUSE Triangle. Names for other types of triangle. Equilateral [ all angles 60 degrees and all sides the me length). Isosceles ; Two angles are equa; and two sides the same length Obtuse ; one angle between 9 degrees and 180 degrees. Right-Angles ; One right angle. Scalene ; three angles unequal and three sides unequal length.
If you have the length of two of the sides and one other angle you can use the law of sines.
An isosceles triangle is a triangle with two equal sides and two equal angles. The two equal sides are called the legs, and the angle between them is called the vertex angle. The two other angles in an isosceles triangle are equal and are called the base angles.
