Answer 1

Answer:

θ ≈ 108.83°

Step-by-step explanation:

$\cos\theta=\frac{0.22}{0.22-1}\\\\\implies\cos\theta=\frac{0.22}{-0.78}\\\\\implies\cos\theta=\frac{-11}{38}\\\\\implies\theta=\cos^{-1}(\frac{-11}{38})\approx108.83$

So, θ ≈ 108.83°

P.S. You have to use a calculator to calculate the arc-cosine.

Hope it helps!
