We know that
180 degrees is equal to pi radians
so
for 30 degrees
180°--------> pi radians
30°--------> x
x=30*pi/180------> x=pi/6 radians
for 60 degrees
180°--------> pi radians
60°--------> x
x=60*pi/180------> x=pi/3 radians
for 90 degrees
180°--------> pi radians
90°--------> x
x=90*pi/180------> x=pi/2 radians
the answer is the option c
pi/6,pi/3,pi/2
Answer:
We'll use the Law of Sines:
Sine (C) / c = Sine (B) / b
Sine (86) / 40 = Sine (52) / b
0.99756 / 40 = 0.78801 / b
0.024939 = .78801 / b
b = .78801 / .024939
side b = 31.5974978949 feet
Sine (42) / a = Sine (86) / 40
(0.66913 / a) = 0.024939
a = .66913 / .024939
side a = 26.8306668271 feet

Inverse is used to find the value of an angle. The inverse of a trigonometric function gives you the angle instead of the ratio. Commonly, these are denoted with the prefix "arc-". So, the inverse of the tan function is the arctan function.
The reciprocal of a trigonometric function is simply its algebraic reciprocal--that is, 1 over the function.
