7.
8.
∠ 2 and ∠ 6 are supplementary;
∠ 4 and ∠ 5 are supplementary;
∠ 5 and ∠ 2 are supplementary; ∠ 1 and
∠ 1 ≅ ∠ 2; ∠ 3 ≅ ∠ 5; ∠ 3 and ∠ 4
∠ 4 are supplementary; ∠ 3 ≅ ∠ 2; ∠ 3
and ∠ 5 are supplementary.
are supplementary.
Given l ||m, m ∠ 1 = 98, and m ∠ 2 = 40, find the measure of
each angle.
9. m ∠ 3
(180 – 98) = 82
10. m ∠ 4
98 (corresponding angles)
11. m ∠ 5
(180 – 98) = 82
12. m ∠ 6
(180 – 40) = 140
13. m ∠ 7
40 (Linear Pair)
14. m ∠ 8
40 (alternate interior angles)
15. m ∠ 9
140 (linear pair)
Find the values of x and y
(9x + 12) + (5x) = 180
16.
14x = 168
x = 12
(6y) + (13y – 10) = 180
19y = 190
y = 10
