Answer:
a = -5
Step-by-step explanation:
15 - a = 20
Move the constant of 15 to the other side by subtracting it.
-a = 5
Divide by -1 to make a positive.
a = -5
Check.
15 - (-5) = 20
15 + 5 = 20
20 = 20
The answers are:
a = cc = db + d =180 degreesHere's how:
When a line intersects two parallel lines, then corresponding angles are formed which means the same corners are congruent.
option c = d is considered.
And, because of vertical angles,
a = d is also an answer.

Answer:
Step-by-step explanation:
A(-2,4),B(-2,1),C(-1,2)
after rotation clockwise
A'(4,2),B'(1,2),C'(2,1)
after translation
D(8,-1),E(5,-1),F(6,-2)
