Answer:

see the procedure

Step-by-step explanation:

we know that

m∠1+m∠2=180° -----> supplementary angles (form a linear pair)

we have

m∠1=27° ----> given problem

substitute the measure of m∠1 in the equation above and solve for m∠2

27°+m∠2=180°

Subtract 27° both sides

27°+m∠2-27°=180°-27° ----> by subtraction property of equality

m∠2=153°

Answer:

The center is (20, 0.05)   radius = 9

Step-by-step explanation:

The center is (20, 0.05)   radius = 9

from the general form of the equation:

(x - h)^2 + (y - k)^2 = r^2

we see that  r^2 = 81

so r = 9
