The value of x is 55.
It is a 90 degree angle so you subtract 90 and 35 to get 55.
Great question! A midpoint is exactly what it sounds like; the point in the middle of two objects (in this case it's the middle of these two coordinates). Another way to think of the middle of something in math is by using the average. To find the midpoint of two points, we just find the average of the x-values and the average of the y-values:
((x1 + x2)/2 , (y1 + y2)/2)
((5 + -13) / 2 , (-4 + 12) / 2)
( -8 / 2 , 8 / 2)
(-4 , 4)
Answer:
Neither
Step-by-step explanation:
142 + 56 = 198º
Complimentary = 90º
Supplementary = 180º
Neither
M midpoint of CD, given
MD = 3, given
MD = CM, def. of midpoint
CM = 3, substitution
