Question

One angle measures 170°, and another angle measures (6k + 44)°. If the angles are vertical angles, determine the value of k.

Answer 1

21 = k

Explanation:

Vertical angles are equal

170 = 6k+44

Subtract 44 from each side

170-44 = 6k+44-44

126 = 6k

Divide each side by 6

126/6 = 6k/6

21 = k
