Determine whether wx←→− and yz←→ are parallel, perpendicular, or neither.

w(−2,−1),x(4,1),y(1,−4),z(5,−4)

Neither

Step-by-step explanation:

We have to determine whether WX and YZ are parallel, perpendicular or neither.

Coordinates are W(-2, -1) X(4, 1) Y(1, -4) and Z(5, -4)

Now we will find the slopes of WX and YZ.

Slope of WX = =  

                     =    =  

Slope of YZ =   = 0

Since there is no relation in slopes of WX and YZ. Therefore, answer will be Neither.

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°

inch

step-by-step explanation:

yard and mile are too big.
