The trapezium PQRS parallel to SR,∠PQS = 34o and ∠SPQ = 2 ∠SRQ. Find the size of, SQR

A.

58o

B.

68o

C.

78o

D.

90o

E.

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

Two angles (a + 31) and (b - 49o) are adjacent angles on a straight line. Which of the following is true

A.

a + b = 198o

B.

a + b = 180o

C.

a + b = 162o

D.

a + b = 100o

E.

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
