Answer: x = 80°, y = 50°
Explanation:
We have an isosceles triangle.
As you can see, 130° lies on a straight line. A straight line = 180°.
The base angles of an isosceles triangle are equal. This means 180° - 130° = y.
So, y = 50°.
The total measures of any triangle is 180 degrees.
The total measure for the base angles here 100 degrees. That is, 50° + 50° =
100°.
How do we find x?
x = 180° - 100
x = 80°
