Answer:
Step-by-step explanation:
We connect the midpoints of any two sides of a triangle with a line segment, then that line segment is following two properties. The line segment will be parallel to the third side. The length of the line segment will be one-half the length of the third side. This is how you prove it.

You could expand terms out and simplify, but I think it's more handy to leave it in this form so you can easily spot the center and radius from a glance.
Answer:
Step-by-step explanation:
If OA is perpendicular to OC, then <OAC = 90°
<OAC = <AOB + <BOC
Given
<AOB = 6x-12
<BOC = 3x+30
On substituting this values into the formula:
6x-12+3x+30 = 90
9x+18 = 90
Subtract 18 from both sides
9x+18-18 = 90-18
9x = 72
x = 72/9
x = 8°
Since <AOB = 6x-12
<AOB = 6(8)-12
<AOB = 48-12
<AOB = 36°
Also <BOC = 3x+30
<BOC = 3(8)+30
<BOC = 24+30
<BOC = 54°
Answer: Y=-1 which means on a graph it would be a horizontal line on the point of (0,-1)
