Question

Find the angle measures. Justify you responses.

Given: a//b, m<3= 63 degrees

Find: m<6, m<7

(The < is used as the angle sign)

Answer 1

i think 89

Explanation:

Answer 2

m∠6 = 117º

m∠7 = 63º

Explanation:

m∠3 = m∠7 = 63º(corresponding angles)

180º - m∠3 = m∠6 = 117º (same side interior angles are supplementary)

or

180º-m∠7 = m∠6 = 117º (linear pair)
