Midpoint (1/2, -5/2)

Step-by-step explanation:

To find a midpoint, add the x's of the endpoints and divide by 2. Then add the y's and divide by 2.

C(-3, -4)

D(4, -1)

Midpoint:

( x+x /2 , y+y /2 )

( -3+4 /2 , -4+-1 /2 )

( 1/2, -5/2)

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
