What type of triangle has an angle of 120 degrees and two angles of 30 degrees?
An isosceles triangle
How many acute sides does an acute triangle have?
First: Sides are not acute or obtuse. ANGLES are acute or obtuse. An acute triangle has to have all angles acute. Examples: 60, 60, 60 70, 60, 50 45, 50, 85 45, 45. 90 30, 60, 90 But if one of the angles is obtuse (>90 degrees), then the other two must be acute. Of course, *this* triangle would not be called an acute triangle, because one of its angles is abtuse; it would be called an obtuse triangle.
A triangle has two equal sides and one angle that is 120 degrees What are the other two angles?
30 degrees each
What is the height of an equilateral triangle with a length of x?
Cutting the equilateral triangle in half results in two right triangles each with a base of length x/2, and angles of 30, 60, and 90 degrees. Using the lengths of sides of a 30-60-90 triangle it can be found that the height is (x/2)√(3), which is the same as the height of the equilateral triangle.So the height of the equilateral triangle is x√(3) / 2.
If two angles of a triangle are acute then the third angle must be?
It can be either acute or obtuse. An acute angle is less than 90 degrees and all 3 angles add to 180 degrees. For example, If two angles are 60 degrees (acute) then the 3rd is 60 degrees (acute). If two angles are 30 degrees (acute) the 3rd is 120 degrees (obtuse).
What type of triangle has interior angles with measures of 30 and 40?
The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
If you have two angles of a triangle that are 30 and 80 how do you find the third angle?
All triangle angles add up to 180, therefore subtract 30 and 80 (110) from 180. The remaining angle is 70.
What type of triangle has angles of 75 75 and 30 degrees?
An isosceles triangle has angles of 75, 75 and 30 degrees.
If the angles in a triangle are 30 degrees 60 degrees and 90 degrees is called what type of triangle is it?
A right angles triangle, as one of the angles in the triangle is 90 degrees.
What triangle has 30 degrees 40 degrees and 110 degrees?
An obtuse angled triangle.
If one the angles of a right triangle is 30 degrees what are the other two angles?
Total sum of angles in a triangle is equal to 180 degrees . Right triangle has a 90 deg. angle so 180-90= 90-30 = 60. The three angles are 90 60 and 30 degrees. == ==
IFan exterior angle of a triangle is 110 degrees and one of the interior opposite angle is 30 degreesfind the other two angles of the triangles?
70 and 80 degrees
A triangle that has angles that measure 30 60 90?
Is a right angled triangle.
What is a triangle with to 30 degree angles and one 120 degree angle?
It is an isosceles triangle.
What is a thirty sixty ninety triangle?
It is a triangle with 90, 60, and 30 degree angles.
How do you classify a triangle with angle measures 110 degrees40 degreesand 30 degrees?
It is an obtuse triangle
If an isosceles triangle has a angle of 30 degrees find the size of the other angles in the triangle?
There are 180 degrees in a triangle, so 180 minus 30 is 150. Since it's an isosceles triangle, that means the other two angles angles are the same, so 150 divided by 2 is 75.
