Which equation could be used to find m∠E in △EFG? m∠E = cos–1(StartFraction 3 Over 4.6 EndFraction) m∠E = cos–1(StartFraction 4.
polet [3.4K]

Answer:

m\angle E=tan^{-1}(\frac{3}{4.6})

Step-by-step explanation:

The picture of the question in the attached figure

we know that

In the right triangle EFG

tan(E)=\frac{GF}{EF} ----> by TOA (opposite side divided by the adjacent side)

substitute

tan(E)=\frac{3}{4.6}

m\angle E=tan^{-1}(\frac{3}{4.6})
