Answer:
x=7
Step-by-step explanation:
We have been given all exterior angles of a quadrilateral which is a polynomial having 4 sides
We know that sum of all exterior angles of a regular polygon is always 360 degree.
So we can all given exterior angles and set it equal to 360
(12x+37)+(12x-2)+(46)+(20x-29)=360
12x+37+12x-2+46+20x-29=360
12x+12x+20x+37-2+46-29=360
44x+52=360
44x=360-52
44x=308
divide both sides by 44
x=7
<u>Hence final answer is x=7.</u>
The coordinates of the point that is one-half the distance between A(-1,-2) and B(6,12) is (2.5,5)
What is the midpoint?
The mid-point lies midway between the two ends. Its x value lies in the middle of the other two x values. Its y value lies in the middle of the other two y values.
Given, 

Let M is a midpoint of AB, then

The midpoint of point AB is M(2.5,5)
Therefore, the coordinates of the point which is one-half the distance between A(-1,-2) and B(6,12) is M(2.5,5).

Answer:
5x=55
Divide both sides by 5 to solve for x
5x/5=55/5
x=11
