Answer:
midline = 1.5
Step-by-step explanation:
f(x) = d + a*cos (bx+c)
a = amplitude
b = part of the period
c = horizontal shift
d = vertical shift (midline location)
d = 1.5

This is a right angle triangle where the hypotenuse a^2 = b^2 + c^2
= 15^2 + 8^2 = 225+64= 289
289= 17^2
17 = hypotenuse
The sine of an angle is the ratio of the shortest side to the hypotenuse
= 8/17= 0.4705
sine^-1 0.4705 = 28°
