Question

Find angle A in the following triangle

35.54 degrees
35.67 degrees
36.24 degrees
36.77 degrees

Answer 1

35.54 degrees

Explanation:

For A, we have the opposite side (5) and the adjacent side (7). We can use the inverse of tan and to tan⁻¹(5/7) to get 35.54

We use the inverse of tan because tanΘ=opposite/adjacent, and we want to find the angle. We multiply both sides by the inverse bc that's what we would do if it was a number, and then get tan⁻¹(5/7)

Hope this helps. Sorry if I added too much explaination
