The ratio of the measures of the sides of a

ANTONII [103]

Answer:

The length of the sides are 8 , 32 , 36

Step-by-step explanation:

Ratio of sides = 2 : 8 : 9

The sides are 2x , 8x , 9x

Perimeter of triangle = 76 inches

2x+ 8x + 9x = 76

19x = 76

x = 76/19

x = 4

2x = 2*4 = 8

8x = 8 * 4 = 32

9x = 9 * 4 = 36

What is the midpoint of a line segment with the endpoints (-4, -3) and (7, -5)

Katyanochek1 [597]

Midpoint Formula: ( $\frac{x+x}{2}$ , $\frac{y+y}{2}$ )
Midpoint = ( $\frac {-4+7}{2}$ , $\frac {-3-5}{2}$ )
Midpoint = ( $\frac {3}{2}$ , $\frac {-8}{2}$ )
Midpoint = ( $\frac {3}{2}$ , -4)
So, the midpoint of the endpoints (-4,-3) and (7,-5) is ( $\frac {3}{2}$ , -4).
Have a nice day! ♪
