Hello!
You can use the Pythagorean Theorem

C is the hypotenuse which is the line across the diameter
a and b are the other sides
You have to find the bottom side of the triangle
9 - 6 = 3
Put in the values you know

Square the numbers

Add

take the square root of both sides

The answer is

Hope this helps!
1/ we make -3*and and we have y=-1 and we replaced to have x=6
2/ any answer x=(7y+3)÷2
If we change answer of x in the second equation we get -7y-3+7y=-3
3/ x=-4+2y we change it in the second equation and we get y =1 if replace it in the first we have x=-2
4/ B=10 and C=16
5/ a= false
b=true
c=true
d=true
Answer:
A
I hope this will help you.
