Answer:
x=20; vertical angles theorem
Step-by-step explanation:
hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.
2x+10=50
2x=40
x=20
x=20 because of the vertical angles theorem.

The greatest common factor of 645 and 570 would be <u>35</u>.
x = -1,-5
X^2 + 3x + 5 = -3x
x^2 + 6x + 5 = 0
(x + 5)(x + 1) = 0
