Question

Use trig to find angles. Solve for x. Round to the nearest tenth of a degree, if necessary. the numbers are 5.4 and 9.9. The angle is x what is the x?

Answer 1

I need to know which side (5.4 or 9.9) is opposite, adjacent, or the hypotenuse relative to angle x. Here are the common cases and the answers (rounded to the nearest tenth):

- If 5.4 is the opposite side and 9.9 the adjacent side: x = arctan(5.4/9.9) ≈ 28.6°
- If 5.4 is the opposite side and 9.9 the hypotenuse: x = arcsin(5.4/9.9) ≈ 33.1°
- If 5.4 is the adjacent side and 9.9 the hypotenuse: x = arccos(5.4/9.9) ≈ 56.9°

(If you meant 9.9 is opposite and 5.4 adjacent, then x = arctan(9.9/5.4) ≈ 61.4°.)

Tell me which side is which and I’ll give the single correct value.
