Answer:

x = 32°

Step-by-step explanation:

First, find the measure of the obtuse angle that constitutes the straight line.

180 - 72 = 108°

(3x + 12)° and 108° are corresponding angles.

Corresponding angles are angles that form when a transverse line cuts across two straight lines. They are in the same position or corner of the line, making them equal to each other.

(3x + 12)° = 108°

3x + 12 - 12 = 108 - 12

3x = 96

x = 32°

Hope that helps.

Is x + 10 a factor of the function f(x) = x3 − 75x + 250? Explain.

lord [1]

Okay, I worked it out and yes, it is a factor. Once you got x=-10, then you plug it into your formula. from there you can work it out like I did and get the answer. You can also input it into a scientific calcuator and figure it out that way. If you need any more help, go ahead and message me. Hope this helps. You can also but it into the box and divide it that way to find out. whichever way is better for you
