Step-by-step explanation:
We are asked to find the value of A. We know from the question that we need to have the sum of -3x and (A)x equal the third term of the original polynomial, which is 2x. written out in an equation, it looks like this.
We can simplify the equation if we add 3x to both sides, which then leaves us with this.
We can further simplify the equation by dividing both sides by x. This leaves us with our last equation for this problem.
Finally, we have our answer. We can also verify that this is a valid integer by multiplying our, now completed, quotient by the divisor and adding the remainder, which in this case, our remainder is 0, so we will not be including it in our operation.
If our calculations were all correct, the product of these polynomials should equal our dividend, verifying our integer is valid; lo' and behold, it is.
The x value will be 109°. The straight line formed a 180° angle. Solving the equation yields the angle.
<h3>What are supplementary angles?</h3>
Supplementary angles are two angels whose sum is 180°. When a straight line intersects a line, two angles form on each of the sides of the considered straight line.
Those two-two angles are supplementary angles in two pairs. That is, if two supplementary angles are adjacent to each other, their exterior sides form a straight line.
The straight line formed a 180° angle. The resulting equation is as follows:
⇒x+42°+29°=180°
⇒x=109°
Hence, the value of the x will be 109°
The complete question is:
AB is a straight line.

➷ Hank charges $75 for a visit plus $45 per hour.
Therefore, for an hour, Hank would charge $120 as 75 + 45 = 120
Mr Fixit:
As it is for one hour, we look at the first function because the time is 'less than or equal to an hour'.
Mr Fixit would charge $95 for an hour.
Therefore, Hank charges $25 more than Mr Fixit.
