What are the vertices of A'B'C' if ABC is dilated by a scale factor of 2? A. A' (0,20), B' (16,12) C' (8,4)
B. A' (0,20) B' (8,12) C' (4,4)
C. A'(0,10) B' (16,6) C'(8,2)
D. A' (0'5) B' (4,3) C' (2,1)

i would really appreshiate some help!

d

step-by-step explanation:

1010: 3030

is it i think

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°

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
