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)

The measure of angle E can be found by the expression . Option 3 is correct.

See the attached figure of right triangle EFG.

In the figure, side EF is 4.6 units, and side FG is 3 units.

It is required to find the value of measure of angle E.

Use the tangent trigonometric ratio to solve the value of angle E as,

Therefore, the measure of angle E can be found by the expression .
