Correct Answer: Option A
Explanation:
< PSQ = < SQR = < SRQ = 24o
< QSR = 180o - 48o = 132o
< PSQ + < QSR + y + 180 (angle on a straight lines)
24 + 132 + y = 180o = 156o + y = 180
y = 180o - 156o
= 24o
< PSQ = < SQR = < SRQ = 24o
< QSR = 180o - 48o = 132o
< PSQ + < QSR + y + 180 (angle on a straight lines)
24 + 132 + y = 180o = 156o + y = 180
y = 180o - 156o
= 24o
