and radius 
is
In your case,
Plug these values into the generic formula and you'll get your equation.
This would be something like [5] or -[-5] which is absolute value (>.<)
Answer:
Yes if Angle 7 and angle 6 are linear pairs in angles created by a straight line that cuts through parallel lines.
Step-by-step explanation:
Remember that two parallel lines that are cut by a transveral will create 8 angles, which will be similar to each other. Making four pairs of congruent angles means that they will be exactly the same angle located in different parts of the system. So if angles 6 and 7 are congruent, and the lines are cut by a transversal, then the lines are parallel.
The answer is B.
Reason: Think of it this way, the bottom number of all 3 fractions are related to 12. 6*2 4*3 and 3*4..
