Question

In the image below if m<1 = 95° and all indicated lines in the diagram that appear parallel are parallel, which of the following is the measure of the angle that forms the linear pair with angle 1?

A. 75°
B. 105 °
C. 85 °
D. 95 °

Answer 1

m<1=95

95+B=180. ( linear pair)

95+105=180

180=180

hence proved
