Solve for the value of X. Round to the nearest whole number.

x = 30º

Step-by-step explanation:

This answer requires trigonometry, specifically, the cosine function. This is because we are given the length of the side adjacent to x and the length of the hypotenuse.

If you recall:

Therefore,

Now, we must use the inverse cosine function on a calculator to figure out the value of x.

Now, we must round it to the nearest whole number, so x = 30º.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
