(9, -1)

Step-by-step explanation:

Midpoint Formula:

Since we already have 1 endpoint and the midpoint, all we need to do is set the equation up to find the other endpoint:

12.5 = (16 + x)/2

25 = 16 + x

x = 9

-4 = (-7 + y)/2

-8 = -7 + y

y = -1

(9, -1)

Step-by-step explanation:

(16 + x)/2= 12.5

16 + x = 25

x = 9

(-7 + y)/2 = -4

-7 + y = -8

y = -1

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
