The graph of a sinusoidal function has a maximum point at (0,5) and then has a minimum point at (27,-5). Write the formula of the function, where x is entered in radians.

If x + 10 = 70, what is x? a. 40 b. 50 c. 60 d. 70 e. 80

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?
