Question

What is the measure of E?

Answer 1

Hello!

Triangles ALWAYS measure 180°. One angle is 25°. In the other side, the length is the same, 10. That must mean that the other angle is also 25°

First add 25 and 25

$25 + 25 = 50$

Now, subtract 50 from 180 because 180 is the total and 2 of the angles measure 50° together.

$180 - 50 = 130$

$\framebox{Your answer is A. 130 \°}$
