sinθ = 1/2 and cosθ = -√3/2, what is the value of θ?
30 0
60 0
90 o
120 o
150 o
Correct answer is E
In the 2nd Quadrant; SINE is the only Positive.
Where θ is 30 for the first quadrant and
150 in the 2nd quadrant which makes COSINE negative
Given that logp = 2 logx + 3logq, which of the following expresses p in terms of x and q?
p = 5xq
p = 6xq
p = x2 + q3
p = 2x + 3q
p = x2q3
Correct answer is E
log p = 2log x + 3log q
log p = logx 2 + logq 3
logp = log x 2q 3
p = x 2q 3
Solve for x: (x2 + 2x + 1) = 25
-6, -4
6, -4
6, 4
-6, 4
5, 5
Correct answer is D
x2 + 2x + 1 = 25
x2 + 6x - 4x -24= 0
x(x + 6) - 4(x + 6) = 0
(x - 4) - (x + 6) = 0
x = 4 or -6 = -6,4

In the diagram above, O is the center of the circle. If ∠POR = 114o, calculate ∠PQR
123o
118.5o
117o
114o
54o
Correct answer is A
Reflex POR = 2PQR
Reflex PQR = 360o - 114o = 246o
PQR = 246/2 = 123o
