Yes because you have to show if the slope is positive or negative

Answer:
53 degrees
Step-by-step explanation:
Vertical angles are congruent so...
65x-12=43x+10
22x=22
x=1
Then add it into the equation of ∠A
m∠A= 65(1)-12
65-12
53
Answer:
The answer is they are congruent.
Step-by-step explanation:
They have two congruent sides and share one side, so they are congruent by SSS.
