In the figure shown, PQs is a straight line. What is the value of < PRQ?
A
128o
B
108o
C
98o
D
78o
correct option: d
< QPR + < PRQ = < RQS
(Sum of two interior angles of a triangle = Opposite exterior angles)
70o + < PRQ = 148
< PRQ = 148o - 70o
= 78o
(Sum of two interior angles of a triangle = Opposite exterior angles)
70o + < PRQ = 148
< PRQ = 148o - 70o
= 78o
