Hey guys, I need help with these Scale factor problems! problems are linked in a screenshot below:

Step-by-step explanation:

It is clear from your answer to the second part that you know the A→B scale factor is the reciprocal of the B→A scale factor. Use that fact for the other two parts of the question.

It is convenient to find a unit length (or the smallest length) on the smaller figure, then see how much that is multiplied by to get the larger figure.

Once you have these ratios, you need to determine what the notation A→B is supposed to mean. Here, we presume it means B/A.

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°
