-2n²+6n+5
g(n)=-2n²+6n+5 is standard form
Answer:
Not sure but it's A
Step-by-step explanation:
Use the formula or complete the square.
The zeroes of the quadratic can be real and rational; real and irrational; complex conjugates.
If the quadratic is ax²+bx+c, x=(-b+√b²-4ac)/2a.
If b² > 4ac the solutions are real. If b²-4ac is a perfect square, the solutions are real and rational; otherwise they’re real but irrational.
If b² < 4ac the solutions are complex.
Angle measure of triangle
= 180 degrees
X = 180- 75 - 50 = 180 - 120 = 60
Ans= 60 degrees
Happy to help. Please mark as brainliest!
A=45 degree I had the same example ... Even if a angle is 90 degrees is not necessarily a right triangle, so the angle A = 45 degrees
