Question

The angle of depression from D to F measures 25°. If EF = 10 yd, find DE. Round your answer to the nearest tenth.

Answer 1

If angle of depression is 25 then the angle of inclination from opposite side should also be 25 right? Alternate interior angles right?
Thus tan 25' = DE/EF [CALCULATE]
Got it? :)

Answer 2

tan 25 = 0.46...?

Answer 3

\[\tan 25 = \frac{ x }{ 10 }\]

Answer 4

Answer 5

So x should be 4.6 then!! :)

Answer 6

my options are:
A) 11.9 yd
B) 14.0 yd
C) 4.7 yd
D) 9.1 yd

so it would be C right? or wrong
