B.) ∠1 and ∠3
D.) ∠2 and ∠4
They both are supplementary angles
Hope this helps!
B and D are both supplymentary angles I hope I gave you a better chance at getting it right sorry I couldn't help more but there is very little info to find the exact awnser to the problem.
Hope this helps:)
G(9,-3) being dilated by a scale factor of 1/3 is G'(3,-1) so D. All I did was divide the coordinates by 3 and there you go.
