Question

In ΔDEF, the measure of ∠F=90°, the measure of ∠E=32°, and FD = 9.6 feet. Find the length of EF to the nearest tenth of a foot.

Answer 1

EF=15.4 ft

Explanation:

I got it right on delta math so ig its right

Answer 2

`EF=15.4\ ft`

Explanation:

we know that

In the right triangle DEF

`tan(E)=(FD)/(EF)` ----> by TOA (opposite side divided by adjacent side)

substitute the given values

`tan(32^o)=(9.6)/(EF)`

solve for EF

`EF=(9.6)/(tan(32^o))=15.4\ ft`
