Answer:
20
Step-by-step explanation:
These are vertical angles, which means that the measurements would be the same. Set the two angles equal to each other.
3x + 50 = 6x - 10
Isolate the variable, x. Subtract 6x and 50 from both sides.
3x (-6x) + 50 (-50) = 6x (-6x) - 10 (-50)
3x - 6x = -10 - 50
Simplify.
-3x = -60
Isolate the variable, x. Divide -3 from both sides
(-3x)/-3 = (-60)/-3
x = -60/-3
x = 20
20 is your answer for x.

Answer:
-4/5
Step-by-step explanation:
use point slope form, which is y2-y1/x2-x1
plug in the numbers to get 10 -(-2)/-7-8. double negatives make a positive, so -2 turns into a positive. so adding them together makes 12/-15. simplify it to get -4/5.
