In a right triangle, given a=32.8 ft and A=28degrees 30'15'',solve for b and c .
:
Convert 28 deg 30 min 15 sec to degrees
28 + + ~ 28.504 deg is Angle A
:
we know
A = 28.504 deg
a = 32.8 ft
Find b, c (b will be the hypotenuse)
:
We can use the sine here, side opposite (a) over hypotenuse
:
Sin(28.504) =
.477 =
.477b = 32.8
b =
b = 68.7 ft length of b
and
Use the cosine to find c (side adjacent over hypotenuse
Cos(28.504) =
.879 =
c = .879 * 68.7
c = 60.4 ft length of c

Was this enough detail for you?
