All triangles have 180 degrees. In this triangle, there is 1 ninety degree angle. The other two are related.

Equation

x + x + 10 + 90 = 180 Combine the left

Solution

2x + 100 = 180 Subtract 100 from both sides

2x+100-100 = 180-100

2x = 80 Divide by 2

2x/2 = 80/2

x = 40

Answer

x = 40

x + 10 = 40 + 10 = 50
