Answer:
D=35
Step-by-step explanation:
First, find a common multiple of both 15 and 6, we get 30, 14/6*5=70/6 meaning that 14/6=35/15

By Sine Rule,
x/sin30° = 8/sin90°
x/0.5 = 8/1
So x = 4.
Answer:
Step-by-step explanation:
tan(30°) = 
cot(30°) = 
sin(60°) = 
Answer:
Due to there being no negatives in this equation, you can pretty much just eliminate the first 3 answers.
However in working out, here is what I did.
x^2 + x - 30 = 12 (+30)
= x^2 + x = 42
Then you can conclude that the answer is D, due to 6 x 6 = 36, plus 7 equaling 42.
