Answer 2

use sin

Answer 3

You are given the hypotenuse which is 20 as well as the side opposite of the angle so we have the hypotenuse and the opposite side so you will use sine...

Answer 4

which means Sin = opp/hyp

Answer 5

Remember: If the number is in the numerator of the fraction you will divide the number by the sin....if the number is in the denominator then you will multiply by sin

Answer 6

You have the side opposite to the angle, and the hypotenuse. SOH is opposite over hypotenuse, so sin35=x/20. Multiply each side by 20, giving you about x=11.47

Answer 7

x=20sin35

Answer 8

So the answer is C

Answer 9

yep
