Answer: 115 degrees
Step-by-step explanation:
(x-5)(x+3)=0
x^2+3x-5x-15=0
(x^2+3x) (-5x-15)
x(x+3) -5(x+3)
x-5=0 x+3=0
x=5 OR -3
Rotation, Translation, and Reflection are the 3 rigid motions that preserve angle measure and side length.
A dilation only preserves angle measure.
Therefore, the answers are A, C, and D
