Does anyone know the answer to these questions? if u do please help me out-1.5m = -2.55 and -4.5 = 1.5 - x

-Yep! I answered both with the steps below :)

Step-by-step explanation:

−1.5m=−2.55

Divide both sides by -1.5.

−1.5m

−1.5

=

−2.55

−1.5

m=1.7

−4.5=1.5−x

Simplify both sides of the equation.

−4.5=1.5−x

−4.5=1.5+−x

−4.5=−x+1.5

Flip the equation.

−x+1.5=−4.5

Subtract 1.5 from both sides.

−x+1.5−1.5=−4.5−1.5

−x=−6

Divide both sides by -1.

−x

−1

=

−6

−1

x=6

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°
