Find the coordinates of the other endpoint of the? segment, given its midpoint and one endpoint.? (hint: let? (x, y) be the unknown endpoint. apply the midpoint? formula, and solve the two equations for x and? y.) midpoint ? ( negative 11 ? 11? , 18 endpoint ? ( negative 5 ? 5? , 10 10? )

We are given mid-point (-11, 18).

One end point (-5, 10).

Let us take coordinate of other end points is (x,y).

Therefore,

Given mid point (-11, 18).

Therefore,

and

Multiplying both sides by 2 in both equations, we get

x-5 = -22 and y+10 =36.

x = -22+5 and y = 36-10

x = -17 and y = 26.

900 degrees

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
