Question

I need help and work shown please help​

Answer 1

F=90

D=37

E=53

f=18.3

d=11

e=14.6

Explanation:

Triangle Sum Theorem means 180-37-90=E. So, E=53 degrees.

Sin(37)=
`(11)/(f)`

fsin(37)=11

f=
`(11)/(sin(37))`

f=18.3

Tan(37)=
`(11)/(e)`

etan(37)=11

e=
`(11)/(tan37)`

e=14.6

Make sure your calculator is in DEGREE mode.
