In the diagram, PQRS is a parallelogram. Find the value of < SQR
Attached Figure / Diagram
A
30o
B
50o
C
80o
D
100o
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
SQR + RQV + VQU = 18o angle on a straight line SP is parallel to QR and PV is parallel to TR
< STP = < RQV = 30o
But SQR + 30o + 50o = 180o
SQR = 180 - 80
= 100o
