Solve for the missing angle

• 122 degrees

• 31 degrees

• 63 degrees

• 95 degrees

Answer explanation

1. Solve for the missing angle in the bottom triangle to be 122 degrees.
2. Remember the second missing angle in the top triangle is a vertical angle to the 122 degree angle in the bottom triangle so it also is 122 degrees.
3. 180-122-27=31
