Which equation represents a circle with center t(5,-1) and a radius of 16 units?

Step-by-step explanation:

The center-radius form (most formally called the standard form) of a circle is (x-h)^2+(y-k)^2=r^2

where (h,k) is the center and r is the radius.

So we have (h,k)=(5,-1) and r=16.

The equation becomes

(x-5)^2+(y-(-1))^2=16^2

(x-5)^2+(y+1)^2=256

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
