You do X2 + 15 and that will be your answer.
By the way, the 2 is a power and is meant to be smaller on top of the X.
Answer:
B. 60 degrees
Step-by-step explanation:
∠6 corresponds to ∠3, which is supplementary to ∠2.
∠6 = 180° -∠2 = 180° -120°

Answer:
-6
Step-by-step explanation:
Multiply the second equation by 2 and add 6x. You get ...
-6x +y = -6
y = 6x -6
This is the same as the first equation when b = -6. That is what you want if you want infinite solutions.
Answer:
x = 67
Step-by-step explanation:
If the measure of the entire chord is 166°, then if you add the two angles that form it together, it will equal 166.
So,
x + 15 + x + 17 = 166
Simplify.
2x + 32 = 166
Subtract 32 from both sides.
2x = 134
Divide both sides by 2.
x = 67
