Step-by-step explanation:
you can start off with the 3x and it's exponent and go on from there
We can use vertical opposite angles. Which means the opposite angles where 2 lines intersects is the same.
3x + 50 = 6x - 10 (vert. Opp. Angles)
3x = 6x - 60
-3x = - 60
X = 20°
Answer: A
I hope its right :)
Answer:
A.5
Step-by-step explanation:
11x+7x+90=180
11x and the unlabeled angle in the triangle are alt. interior and are equal
18x=90
divide both sides by 18
x=5
