Answer:

x= 61 degrees

Explanation:

1. To use trigonometry, you need to take into consideration SOH CAH and TOA. SOH is for sine, CAH is for cosine, and TOA is for tangent.

2. Figure out which one of these you can use. In this case, that would be CAH, which means you use cosine.

3. CAH means the cosine of x equals the adjacent over the hypotenuse. Adjacent is the value that is next to the angle. The hypotenuse is the value of the slant.

4. With that in mind, all you do is plug it into a calculator like so: 3.8/6.2

5. Lastly, you take that answer, move the decimal point up two places, and that's your answer.

\cos(x) = (b)/(h) = (3.8)/(6.2) \\ \cos(x) = 0.612 \\ x = \cos^ {- 1} (0.612) = 51 \degree
