Question

Find the value of x in the triangle shown below.
=
x
31°
77

Answer 1

Answer:

72 degrees

Step-by-step explanation:

You did not show the triangle but I assume that I am to solve for x's angle.

All triangles have 180 degrees. We know two of the angles, 31 and 77. We can subtract them from 180 to get 72 which would be x.
