Answer:
The angle is 120 degrees.
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
So if our angle is x it's supplement is 180 - x.
So we have the equation:
x = 2(180 - x)
x = 360 - 2x
3x = 360
x = 120 (answer).
Answer:
A
Step-by-step explanation:
Given a quadratic equation in standard form : ax² + bx + c = 0
Then the discriminant Δ = b² - 4ac informs us about the nature of the roots.
• If b² - 4ac > 0 then 2 real, distinct roots
• If b² - 4ac = 0 then 2 real , equal roots
• If b² - 4ac < 0 then 2 non real roots
x² + 6x + 14 = 0 ← is in standard form
with a = 1, b = 6, c = 14, then
b² - 4ac = 6² - (4 × 1 × 14) = 36 - 56 = - 20
Since b² - 4ac < 0 then 2 non real roots → A
Answer: 20 + x
Why you ask? Well its just plain logic if you read it thoroughly
