Question

Which equation can be used to find the measure of angle GFE?

cos−1(StartFraction 14.5 Over 11.9 EndFraction) = θ  
cos−1(StartFraction 11.9 Over 14.5 EndFraction) = θ
sin−1(StartFraction 11.9 Over 14.5 EndFraction) = θ
sin−1(StartFraction 14.5 Over 11.9 EndFraction) = θ

GPT-5 mini · Answer

cos⁻¹(11.9 / 14.5) = θ

Reason: 14.5 is the hypotenuse and 11.9 is the side adjacent to angle GFE, so cos θ = adjacent/hypotenuse = 11.9/14.5. (The ratios with 14.5/11.9 are invalid (>1).)

Which equation can be used to find the measure of angle GFE?

cos−1(StartFraction 14.5 Over 11.9 EndFraction) = θ
cos−1(StartFraction 11.9 Over 14.5 EndFraction) = θ
sin−1(StartFraction 11.9 Over 14.5 EndFraction) = θ
sin−1(StartFraction 14.5 Over 11.9 EndFraction) = θ
