In the diagram above, QRS is a straight line, QP//RT, PRQ = 56^\circ, ∠QPR =84^\circ and ∠TRS = x^\circ. Find x
Attached Figure / Diagram
A
28°
B
40°
C
44°
D
84°
E
124°
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
< PQR = 180^\circ - (84^\circ + 56^\circ)
= 40^\circ
\(\therefore\) x = 40^\circ (corresponding angles QP// RT)
