Question

In this triangle, which of the following is true?

Answer 1

x = 55

Explanation:

For the angles, we have 35, 90, and x. the 90 degree angle is indicated by the square in the triangle. All triangles add up to 180. With that information we can do:

35 + 90 + x = 180

125 + x + 180

-125 -125

x = 55
