Question

6. One of the angles of a triangle is 100° and the other two angles are equal. Find the measures of each of
the equal angles.

Answer 1

Answer:

40°

Step-by-step explanation:

If the other two angles of the triangle are equal, then it means that the triangle is an isosceles triangle.

Let us take the angles as x.

100° + x + x = 180° (angle sum property)

100° +2x = 180°

2x = 180° - 100°

2x = 80°

x = 80/2

x = 40° ==> Ans
