Answer:
35.54 degrees
Step-by-step 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
