We know that mid - point of a line segment divides it into two equal parts, that is it divides the segment in the ratio of 1 : 1, so let's find the coordinates of the mid point of line segment joining points (-9 , 3) and (5 , 7).

let the coordinates of the points be x and y, now

  • m = 1

  • n = 1

  • x_2 = 5

  • x_1 =  - 9

  • y_2 = 7

  • y_1 = 3

Using section formula :

value of x :

  • x =  \dfrac{mx_2 - nx_1}{m + n}

  • x =  \dfrac{(1 \times 5) - (1 \times  - 9)}{1 + 1}

  • x =  \dfrac{5 - ( - 9)}{2}

  • x =  \dfrac{5 + 9}{2}

  • x =  \dfrac{14}{2}

  • x = 7

value of y :

  • y =  \dfrac{my_2 -ny_1 }{m+ n}

  • y =  \dfrac{(1 \times 7) - (1 \times 3)}{1 + 1}

  • y =  \dfrac{7 - 3}{2}

  • y =  \dfrac{4}{2}

  • y = 2

So, coordinates of the point which is midpoint of the given line is :

\boxed{ \boxed{ (7, 2)}}

The perimeter of a triangle is 70 in. The shortest side is 11 in. less than the longest side. The middle side is 24 in. less tha
kondor19780726 [428]

Answer:

The sides are

6

inches,

8

inches and

10

inches

Explanation:

I'd suggest that the question should read 'The perimeter of a triangle is 24 inches. The longest side is 4 inches longer than the shortest side, and the shortest side is three-fourths the length of the middle side. How do you find the length of each side of the triangle?'

In this case the question can be answered. If

x

is the length of the middle side, then the shortest side is 3/4x and the longest side is 3/4x+4

x+3/4x+3/4x+4=24

10/4x=20

x=8

Then the shortest side is 6and the longest side is 10

six angles of a heptagon measure 107, 139, 131, 110, 145. and 128. what is the measure of the seventh angle​
alexgriva [62]

the measure is 140, I basically summed all of the angles of a polygon of “n”, which is 7, then I did 7-2 times 180 (900) so I can finally add up all of your measurements
