Question

A triangle has two equal sides a. one of the angles in this triangle measures 100° What is the size of each of the other two angles?​

Answer 1

Explanation:

Important things to know:

The sum of the angles in any triangle is equal to 180º

An isosceles triangle has two angles that are equal in measurement, while the third one is not

Answer 2

40 degrees.

Explanation:

As it has 2 equal sides it is an isosceles triangle and it also has 2 equal angles. The other angle cannot be 100 degrees because that is greater than 180 degrees, so the two equal angles must sum to 180 - 100 = 80 degrees.

Each angle measures 40 degrees.
