Answer:
I don't think any of the answers here are right. They aren't a proportional relationship since they don't pass through the origin. So I would believe the answer would be C. Sorry if I'm wrong!!
Step-by-step explanation:
I learned about this stuff :D
The answer is 31.4. I hope this helps.
Answer:
3/4
Step-by-step explanation:

Effectively, divide both numerator and denominator by their greatest common factor, 12.
There's no such thing as the "length"of an angle.
But we know what you're getting at.
You have said that the angles are complementary. If two angles are
complementary, then their sum is 90 degrees, so we can take your
two angles and write:
<u>x</u> (one angle) plus <u>(2x + 12)</u> (the other one) <u>= 90 degrees
</u><u /> x + 2x + 12 = 90<u>
</u>Subtract 12 from each side: x + 2x = 78
Add the x's on the left side: 3x = 78
Divide each side by 3 : x = 26 degrees
One angle is 'x' = <em>26 degrees</em>
The other one is (2x + 12) = 52+12 = <em>64 degrees</em>
Y intercept is (0,-2)
Zeros are the x intercepts which are (-7,0) (-3,0) (5,0)
