In the diagram, QP//ST:PQR = 34o qrs = 73o and Rs = RT. Find SRT
Attached Figure / Diagram
A
68o
B
102o
C
107o
D
141o
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
Construction joins R to P such that SRP = straight line
R = 180o - 107o
< p = 180o - (107o - 34o)
108 - 141o = 39o
Angle < S = 39o (corr. Ang.) But in \(\bigtriangleup\)SRT
< S = < T = 39o
SRT = 180 - (39o + 39o)
= 180o - 78o
= 102o
