Question

Geometry. Cosines/ Sines. Find x and round to the nearest tenth. Include explanation if possible and a clear answer. Irrelevant answers will be reported

Answer 1

To answer this, you must first know what SohCahToa is:

Sin - opposite over hypotenuse

Cosine - Adjacent over hypotenuse

Tangent - Opposite over adjacent

In this situation, you need to use Tangent since the 8 is opposite from the X and the 10 is adjacent. So now calculate using the inverse of tan to find the angle. Tan^-1 (8/10)

Answer is 38.7 degrees
