For a particular angle theta, the cosine function f(x) = a cos b(theta) has the following values within one cycle of the functio

Anton [14]

For function $f(x)=a\cos b\theta$ we have that $f(0) =4,\ f( \frac{\pi}{2} )=-4,\ f(\pi)=4$ . This means that period of cosine function is π. Then from the formula for period $T= \frac{2\pi}{b}$ you obtain that $\pi= \frac{2\pi}{b}$ and b=2.

So, the function is $f(x)=a\cos 2\theta$ . If f(0)=4, then $a\cos0=4$ and, respectively, a=4.
Answer: $f(x)=4\cos 2\theta$ .

What is the measure of ∠x?

Dima020 [189]

The angle is a complementary angle so both angles add up to 90 degrees

Therefore set your equation equal to 90 to find angle of x

53+x=90

Subtract 53 from both sides

X= 37 degrees
