Question

If m∠Y = 107° and m∠Z = 33°, what is m∠X?

(Start with the sum of the angles of a triangle
and work backwards.)

A. m∠X = 27° C. m∠X = 33°

B. m∠X = 40 D. m∠X = 120

Answer 1

B would be the answer.

Explanation:

Use what they said. All angles in a triangle would sum to 180 degrees.

So based on that, 107 + 33 + <x = 180

140 + <x = 180

<x would then be 40 degrees
