What angle is the antenna?

It's a shame I can't figure out something I should have learned
in the 6th grade; but I don't know how to set the problem up.

Thanks,

Hi Zack,

Well, not 6th grade material, but for my students in the Navy (and I
sure didn't invent this memory aid):

For the conventional usage
S sine C cosine T tangent O opposite A adjacent H hypotenuse
where you choose one corner or angle (but not the right angle) of any
right triangle and the terms mean:
O the length of the side Opposite that angle
A the length of the side Adjacent to the angle
H the length of the Hypotenuse

O
S = ----
H

A
C = ----
H

O
T = ----
A

What kept it in memory. Reading down columns gives
S C T O H A H O A
or
Sally Could Tell Oscar/Had A/Hard On/Always

You know the Opposite (26) and the Hypotenuse (73) which would give
you the sine (0.3562), take the arcsin of this value to find the angle
(21°).
