Since the triangle is isosceles, the angles that are not on the 87 are both equal.

The other 2 angles can be solved like this
2x + 87 = 180
2x = 180 - 87
2x = 93
x = 93/2 = 46.5 degrees or B

Hello!

To solve this we subtract the angle from the line

180 - 87 = 93

Then we divide by 2

93 / 2 = 46.5

The answer is 46.5

Hope this helps!
