Answer:
Step-by-step explanation: one angle is 6x + 9 also equals to 9x -30
9x - 30 = 6x + 9
3x = 39, x = 13
Angle is 6×13+9 = 87
Rule needed: i^2 = -1
Standard form a + bi
(3 + 2i)(7 - 5i) FOIL
3 * 7 = 21
3 * - 5i = - 15i
2i * 7 = 14i
2i * -5i = - 10i^2 = - 10 * -1 = 10
Putting it all back together.
31 - i
