Find the midpoint of cd if c= (9,2) d= (-7,-9)

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)

angle q= 92 degree

step-by-step explanation:

the solution is in the picture

when a quadrilateral is inscribed in a circle, the opposite angles are supplement to each other. in other words, the sum of the 2 angle is 180 degree

45
