Can u help me pls
I don”t know what to do

Step-by-step explanation:

Do you know SOHCAHTOA

Sin = opposite/hypotenuse

Cosine = adjacent/hypotenuse

Tangent = opposite/adjacent

#1

We have to find cos(x) = adjacent/hypotenuse

#2:

We are given an angle of 30 degrees and an opposite side of 15

We need to find the adjacent side, so we can use Tangent

#3

We are given an angle and an opposite side and we have to solve for hypotenuse.

We can use sin

#4:

We are given two sides, we have to find the angle. We are given an opposite side and an adjacent side, so we can use arctangent (, but not 1/tan(x))

#5

We are given an opposite side and the hypotenuse, we can use sin
