10) because of the alternative exterior angle theorem angle 2 is the same as angle 8 and because of the vertical angles congruence theorem angles 2 and 4 are also the same so if angle 2 is the same as both 4 and 8,
then x=5 because 4x+57 =77
subtract 57 from both sides and 4x=20
divide both sides by 4 and x equals 5
Here is my answer.. correct me if im wrong.
Answer: What?
Step-by-step explanation:
Answer:
A number line going from negative 4 to positive 4. Points are at negative 4 and positive 4.
<span>Move all terms containing x to the left, all other terms to the right.
Add '-240' to each side of the equation.
240 + -240 + 12x = 372 + -240
Combine like terms: 240 + -240 = 0
0 + 12x = 372 + -240
12x = 372 + -240
Combine like terms: 372 + -240 = 132
12x = 132
Divide each side by '12'.
x = 11
Simplifying
x = 11</span>
