To find the midpoint of a segment you need to use this equation:
(x1+x2/2, y1+y2/2) so if you plug in the numbers its...
9+(-7)/2, 2+(-9)/2
then solve to find x and y coordinate
x= 1 and y= -3.5
so the midpoint of CD is (1,-3.5)
90000 is the significant figures
Answer:
x=90
Step-by-step explanation:
So, since x-20 is the vertical angle directly near 70, we can say:
x-20=70.
if we solve x is 90.
