Answer:
they are =
im sorry it was a little late
The trick to solving this problem is to know and remember that the sum of all the interior angles of a triangle is always 180 degrees.
Thus, (6x+1) + (5x-17) + (9x-24) = 180.
20x = -40, so x = -2 (answer)
Polynomial with real coefficients always has even number of complex roots. We know that one of them is 2 + 5i so the second one will be 2 - 5i and:

Answer B.
If two angles are supplementary, their sum equals 180 degrees
Answer:
7.72 * 10^15
Step-by-step explanation:
8*10^15 - 2.8*10^14 = 7.72 * 10^15
