The answer is C. You would subtract the angle from a straight line, or 180.
you will have to multiply 23 by 8 which equals 184. the tickets will be 184 dollars

Answer:
The price before increase = 1255.5
Step-by-step explanation:
7% of 1350 =
= 94.5

Answer:
x = ± sqrt(-49)
or x = ± 7i
Step-by-step explanation:
x^2 +49 = 0
Subtract 49 from each side
x^2 +49 -49 = 0-49
x^2 = -49
Take the square root of each side
sqrt(x^2) = ± sqrt(-49)
x = ± sqrt(-49)
We have to complex numbers to solve
x = ± sqrt(-1) sqrt(49)
sqrt(-1) = i
x = ±i *7
x = ± 7i
