Find the value of m in the diagram
A.
34o
B.
27o
C.
23o
D.
17o
Correct answer is D
△ ABC, A + 153 = 180 (angles on straight line)
< A = 180 - 153 = 27
< B = 2m(vertically opposite angles)
< C = 7m (corresponding ngles)
< A + < B + < C = 180 (sum of int. angles of △)
i.e. 27 + 2m + 7m = 180o
9m = 180 - 27
9m = 153
m = 1539
= 17
