Segment AB has endpoints A(-3,1) and B(2,-6). Suppose that point B is translated to B'(-1,-8). (a) How far away is point B from point A? (b) How far did point B move to get to point B'?

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°

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

the correct answer for this just to make it clear for you guys is 2,3
