What are the amplitude and midline?
I WILL MARK BRAINLIEST IF CORRECT.

see explanation

Step-by-step explanation:

The amplitude is the value from the x- axis to the maximum, thus

amplitude = 2

the midline is the line midway between the minimum and the maximum

Assuming the graph is symmetrical about the x- axis

Then the max is 2 and the min is - 2

y = = = 0

Thus the midline is y = 0

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

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°
