Question

which equation can be used to find the measure of angle gfe?
○ $sin^{-1}left(\frac{11.9}{14.5}
ight)=\theta$
○ $sin^{-1}left(\frac{14.5}{11.9}
ight)=\theta$
○ $cos^{-1}left(\frac{11.9}{14.5}
ight)=\theta$
○ $cos^{-1}left(\frac{14.5}{11.9}
ight)=\theta$

Explanation:

Step1: Identify angle GFE components

Assume right triangle GFE with angle θ at F, hypotenuse 14.5, adjacent side 11.9.

Step2: Apply cosine definition

cosθ = adjacent/hypotenuse = 11.9/14.5 → θ = cos⁻¹(11.9/14.5)

Answer:

B. cos⁻¹(11.9/14.5) = θ
