Answer:
(c) 31.2-60
Step-by-step explanation:
Given that
60 – 31.2 + ? = 0

This is the same as the expression in option (c) 31.2-60.
Hence, option (c) is correct.
Answer:
The correct answer is m=
and θ = 30º.
Step-by-step explanation:
First, we must form a triangle whose hypotenuse is the radius r=1, its adjacent leg is m, its opposite leg is
and the angle is theta.
First, we calculate the angle with theta's breast:
sin (θ) = 
where H is the hypotenuse, in this case, the radio.
θ =
(
)
θ = 30º
Now, we calculate the adjacent leg, which is equal to the x-coordinate of the point:
cos (θ) = 
m = cos 30º * H
m = 
m = 
Have a nice day!
