PLEASE HELP EXPLAIN THIS

Step-by-step explanation:

Look at the number and the angles

Multiple the angles all together that's how u find x

The answer for number one is X=37. This is because 37 is half of 74.

Basically, these are all equal angles. The ones across from eachother are, and the angles that are right next to eachother are always going to equal 180, or half of 360. Number 4 is the same as the rest, but it seems more confusing because of the 5th line. If you add 55 and 85, then divide it by 8, you will get the answer.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
