Answer:
-2x
Step-by-step explanation:
x^2-10x+24
-20x+24
4x
x-6= -6x
4x-6x
4-6=-2
bring down the x and you get -2x

Answer:
7.7
Step-by-step explanation:
Hi!
These two angles are alternate interior angles, so they are congruent. Thus:
∠A = ∠B
6x + 5 = 4x + 45
Solve for x:
2x + 5 = 45
2x = 40
x = 20
Solve for ∠A by substituting in this value:
∠A = 6(20) + 5 = 125°
