Question

A triangle has two equal angles and a smaller angle which measures 26 degrees. What is the measure of one of the larger angles.

Answer 1

A  triangle has 3 angles and they always add up to 180 degrees. If the first angle is 26, subtract 26 from 180, which is 154. If the other two angles are equal, divide 154 by two, which is 77. So the other two angles are both 77

Answer 2

180 = 2x + 26
-26          -26
154 = 2x
÷2      ÷2
77 = x
One of the sides is 77
