Help me with trig please, I don’t need in-depth solution, I’m just checking my answers:)

Answer 1

Answer:

The value of x = 60.8°

Step-by-step explanation:

Given:

angle = x

hypotenuse = 39

adjacent = 19

To find:

The value of x

To find the value of x, we will apply cosine rule (CAH):

`cos\text{ x = }(adjacent)/(hypotenuse)`
`\begin{gathered} cos\text{ }x\text{ = }(19)/(39) \\ cos\text{ x = 0.4872} \end{gathered}`
`\begin{gathered} x\text{ = cos}^(-1)(0.4872) \\ x\text{ = 60.84\degree} \\ \\ The\text{ value of x to the nearest tenth is 60.8\degree} \end{gathered}`
