Question

Solve for theta to the nearest degree​

Answer 1

Step-by-step explanation:

So first thing is to determine which trigonometric ratio we use here. Theta is adjacent to 5 and 8 is the hypotenuse, so we should be using Cosine.

So we set up the equation

cos θ = adj/hype

cos θ = 5/8

θ = $cos^{-1} (5/8)$

θ=51.3178125...

θ=51°
