The answers 9. I took the test :)
Use this equation: A=3.14159r^2
Answer:
D.) 1:6
E.) 8:48
Step-by-step explanation:
Y=2x+4
y=2x-4
and the last one is already in standard form
The reasons would be:
alternate interior angles
vertical angles
AAA (all angles are congruent)
Since we know that the two line segments are parallel, this means that BC is a transversal. Using that knowledge with the position of ABE and DCE, we see these are alternate interior angles.
AEB and DEC are vertical angles, since they share only a vertex.
This gives us 3 congruent angles, so the triangles must be similar.
