[1st Picture] Answer: x = 3.98

Explanation:

We are given the opposite side and adjacent side from our reference angle. This will use the tangent function. tanθ =
(opposite)/(adjacent).

tan(53°) =
(x)/(3)

3tan(53°) = x

x = 3.98

[2nd Picture] Answer: x = 3.13

Explanation:

Here, we are given the opposite side from our reference angle and the hypotenuse. This will use the sine function. sinθ =
(opposite)/(hypotenuse).

sin(23°) =
(x)/(8)

8sin(23°) = x

x = 3.13

[3rd Picture - #6] Answer: θ = 63.4°

Explanation:

Again, we are given the opposite side from our reference angle and the hypotenuse. This will use the sine function. sinθ =
(opposite)/(hypotenuse). To find the angle measurement of theta at the end, we will use the inverse of sine.

sin(θ) =
(6)/(6.71)


sin^(-1)(sin(θ)) =
sin^(-1)(
(6)/(6.71))

θ = 63.4°
