When two lines intersect, (in this case it's a ray and a line), they form a linear pair. Here, we know that because those two angles form a linear pair. Solving for x we have :
The angle is a straight angle. Straight angles measure 180°. One of the angles measures 93°. Subtract 93 from 180.
That means:
Switch it around and it becomes:
The sign changes when you move it to the other side. at first you were adding, and now you're subtracting.
Subtract:
Divide both sides by 3 to leave the variable alone:
That means x = 23

Answer:
8
Step-by-step explanation:
We can use the Polynomial Remainder Theorem. The PRT states that if we have a polynomial being divided by a factor in the form of
, then the remainder of the polynomial is given by
.
We have the polynomial:
And it is being divided by:
We can rewrite our factor as:
Therefore:
Then our remainder will be:
Evaluate:
So, our remainder will be 8.
