Answer:

A. 21, 16, 28

Step-by-step explanation:

1st side = x

2nd side = x-5

3rd side = x+7

x+x-5+x+7 = 65

3x + 7 - 5 = 65

3x + 2 = 65

3x = 65-2

3x = 63

63/3 = 21

x = 21

therefore, the sides are 21, 16, and 28

Find the distance and midpoint for the following coordinates.<br> P(7.6 , 10.1) and Q(4.6 , 3.1)
KATRIN_1 [288]
Solving for the midpoint:

x - coordinate: (7.6 + 4.6)/2 = 6.1
y - coordinate: (10.1 + 3.1)/2 = 6.6

Midpoint: (6.1 , 6.6)

Solving for the distance:

Distance formula: sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

D = sqrt( (7.6 - 4.6)^2 + (10.1 - 3.1)^2 <span>)
D = sqrt( 3^2 + 7^2)
D = sqrt(58)
D = 7.62 units

Distance = 7.62 units</span>
