Question

The exterior angles of triangle UVW are ∠X, ∠Y, and ∠Z, and they are adjacent to ∠U, ∠V, and ∠W, respectively.

If m∠U is 27°, and m∠Y is 86°, what is m∠W?

Answer 1

Answer:

m∠W = 67°

Explanation:

According to the triangle sum theorem, three angles added up together in a triangle must be 180°. To find the missing angle:

86°+27°+x°=180°

= 67°

Answer 2

Answer:

59 degrees!!!!!!
