Answer: 33%
Step-by-step explanation: 5/15 simplifies to 1/3 which is 33%
39 degrees. All angles must add up to 180 and the two acute angles equal each other because of the type of triangle it is!
Answer: Yes.
Step-by-step explanation: Because if it is 0 on the x axis then no matter what the Y number is it will be on the line.
Assuming you are speaking of the Real Numbers…
x^2+66=14x+15
x^2 - 14x + ?? = -51
x^2 - 14x + (half of -14 squared) = -51 + (half of -14 squared)
x^2 - 14x + 49 = -51 + 49
(x - 7)^2 = -2
By the way, in the real number system, you can’t square any number and get a negative so the above equation has no solution. If you allowed for complex solutions…there would be two of those.
