1. What is the value of 0 for the acute angle in a right triangle?
2. Roman stands across from a flag pole. What is the distance from Roman's feet to the base of the flag pole? Round only your final answer to the nearest tenth.
Sine and cosine are co-functions.....
sin (90- theta) = cos(theta)
sin (90-73) = cos(73)
sin (16°) = cos (73°)
For the second one, we are given an angle, the hypotenuse and we are trying to find the adjacent side......the cosine seems appropriate
cos (39) = x / 17 multiply both sides by 17
17 * cos(39) = x ≈ 13.2 m
