Answer:
The answer to your question is: x1 = - 7 + 9i x2 = -7 - 9i
Step-by-step explanation:
x² + 14x = - 130
x² + 14x + (7)² = -130 + (7)²
(x + 7)² = -81
x + 7 = ± √-81
i² = -1, then x + 7 = ±√ 81i²
x + 7 = ± 9i
x1 = -7 + 9i x2 = -7 - 9i
The answer is 6 & 7.
6 * 7 = 42
6 + 7 = 13
The two horizontal lines are parallel.
This makes the 80 degree angle and the angle ox x and 20 degrees are alternate interior angles and are the same.
This means x + 20 needs to equal 80.
X = 80-20 = 60 degrees.
