Refer to the figure at the right. Line a is parallel to line b
and m∠2 is 145°. Find each given angle measure. Justify
your answer.
11.
m∠9
55°; Sample answer: ∠2 and angles 9 and 10 are
vertical angles. So, m∠9 + m∠10 = 145°. So, m∠9 =
145 − 90 or 55°.
12.
m∠7
145°; Sample answer: ∠2 and ∠7 are alternate
interior angles. So, m∠7 = 145°.
