Answer:

x = 20

Step-by-step explanation:

Two lines are parallel. So, alternate interior angles are congruent.

x +8 + 6x - 58 = 90

7x - 50 = 90

7x = 90 +50

7x = 140

x = 140/7

x = 20

Answer: n=4

Step-by-step explanation:

$\left(-9\right)-9n=\left(-45\right)$

$-9n=-36$

divide both sides by -9
