Question

I need help with this page

Answer 1

Remember,

sin = op/hyp

cos = adj/hyp

tan = op/adj

For question 3 it would be B and C, because the adjacent side of angle x is 12, the hypotenuse is 37, and cos = adj/hyp.  Also, the opposite side of angle z is 12, and the hypotenuse is 37, and sin = op/hyp.  So both answers would be 12/37. You would do the same with question 4.

For 5, you would do the same thing.  It would be D because you can only take the sin of angle 24, and x is a side.  the opposite of 24 is x and the hypotenuse is 11, so sin 24 would be x/11. It is the same for problem 6.
