Question

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 4.6 Over 3 EndFraction) m∠E = tan–1(StartFraction 3 Over 4.6 EndFraction) m∠E = tan–1(StartFraction 4.6 Over 3 EndFraction)

Answer 1

Answer:

Answer:

Step-by-step explanation:

The picture of the question in the attached figure

we know that

In the right triangle EFG

----> by TOA (opposite side divided by the adjacent side)

substitute

Answer 2

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

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

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