Answer:

x° = 50°

Step-by-step explanation:

This is an isosceles triangle because two legs are equal (7).  Thus, there are two equal angles, x° and x°, and the three angles must add up to 180°.

Subtracting the 80° angle from both sides, we get 2x° = 100°, which tells us that x° = 50°.

A triangle must equal 180 degrees. Subtract 80 from 180=100. Then divide by 2 to get x. X=50 degrees
