In the diagram above, lines K and L are parallel, and lines Mand N are parallel. If b = 8, then a =?
Correct Answer:
11
Explanation/Reference:
The labeled angle formed by lines M and K and the supplement of the labeled angle formed by lines L and
N are alternating angles. Therefore, they are congruent. The angle labeled (10a + 5) and its supplement,
which is equal to (8b + 1), total 180 degrees: (10a + 5) + (8b + 1) = 180. If b = 8, then:
(10a + 5) + (8(8) + 1) = 18010a + 70 = 18010a = 110a = 11
