In the diagram above, AB, CD and XY are straight lines intersecting at W. Find ∠CWX
20o
80o
100o
120o
140o
Correct answer is B
a = 40o (vertical opp. ∠s are equal) b = 60o
a + b + c = 180o (sum of ∠s on a str line)
40o + 60o + c = 180o
C = 180o - 100o
C = 80o
The trapezium PQRS parallel to SR,∠PQS = 34o and ∠SPQ = 2 ∠SRQ. Find the size of, SQR
58o
68o
78o
90o
112o
Correct answer is D
considering SPQ
S = 34o (base ∠s of Isos. Δ)
P = 180o - 68o = 112o
R = 122/2 = 56o
a = 34o (alt ∠s)
SQR = 180o - (56 + 34)
180o - 90o = 90o
a + b = 198o
a + b = 180o
a + b = 162o
a + b = 100o
a + b = 80o
Correct answer is A
a + 31 + b - 49 = 180o(sum of angles on str line)
a + b - 18 = 180o
a + b = 180 + 18
a + b = 198o
In the diagram above, ∠SPQ = 79o. Find ∠SRQ
11o
391/2
79o
90o
