1) Quadrillateral ABCD is circumscribed about circle O. AB=7, BC=11 DC=8. Find AD.

2) Find the center and radius of the equation: X(squared)-12x+y(squared)+14y+4=0

3) Find the intersection point(s) of the equations:
5x+6y=30
x(squared)+y(squared)=25

Alright i solved 1 of them. Now i still need to know...

1) Quadrillateral ABCD is circumscribed about circle O. AB=7, BC=11 DC=8. Find AD.

and

2)Find the intersection point(s) of the equations:
5x+6y=30
x^2+y^2=25

1) sketch a circle with a circumscribed quadrillateral. notice that the diameter can help you make a triangle.

2) try sketching the graphs. Both equations are of specific type so you will see the answer
 
And what are you thoughts on these two ..? We only can help you when you show how you tried to tackle the question to see where your problems are. For 2) drawing a picture might be a good start. We're not going to do your homework for you, and btw there is a homework help section here dedicated to this kind of question.
 
Can someone please merge these threads und move them to the homework section?
