In the diagram, /MN/, /OP/, /QOP/ = 125o. What is the size of < MQR?
11o
120o
130o
160o
Correct answer is B
< NOP = 180 - 125 = 55o(< s on a straight line)
But < NOP = < ONM (alternate < s)
< ONM = 55o
< M + < N + < MQN = 180o (sum of interior < s of a \(\bigtriangleup\)) i.e
65o + 55o + < MQN = 180
< MQN = 180 - 12o = 60
< MQR + < MQN = 180 (< s on straight line)
< MQR + 60 = 180
< MQR + 60 = 180
< MQR = 180 - 60
= 120o

52
50
48
40
Correct answer is A
2 + 2 + 5 + 8 + 12 + H + 7 + 3 + 2 = 52
Find the size of the angle marked x in the diagram.
108o
112o
128o
142o
Correct answer is C
x + 52o = 90
x = 90 - 52
x = 38o
k = opposite angle Z
k = 38o
y + k = 90o
y + 38o = 90o
y = 90o - 38o
y = 52o
y = x = 180o(sum of angles on straight line)
52 + x = 180o
x = 180 - 52
x = 128
