Question

Find unknown side lengths and angle measures. Please help see picture

Answer 1

Need help finding these
measurement of angle D as listed below and the 2 segments
m <D
DE =
EF=

Answer 2

Angle D can be found using angle sum of a triangle

D = 180 - 90 -51

For DE use sin(51) = DE/18

for EF use cos(51) = EF/18

hope it helps

Answer 3

duh I get how to get the angle measure of D - sorry I should have known that one

Answer 4

is this right
DE = 12.06
EF = 13.36??

This doesn't look right when DF = 18
