Step-by-step explanation:
18/s = 3
Multiply each side by s
18/s *s = 3*s
18 =3s
Divide each side by 3
18/3 =3s/3
6 =s
We know that triangle COW is a right triangle by the Tangent to a Circle Theorem.
So, we can use Pythagorean Theorem to find OW.
OW² + WC² = CO²
OW² + 15² = 17²
OW² + 225 = 289
OW² = 64
OW = 8
I think it is 124 you would take 31*4
