Answer 1

If a radius is drawn to a tangent of a circle at the point of tangency, a right angle is formed. So, Triangle BAO is a right triangle. What does BO=?

Answer 2

35

Answer 3

Yes, then let tangent AB be T. So, T² + 21² = 35² Solve that for T and you will know the length of tangent AB.

Answer 4

ill help you out

Answer 5

T² + 21² = 35²
T² = 35² - 21²
T² = 1225 - 441
T² = ?
T = ?

Answer 6

so just find what 1225-441 equals and take the square root of that. ^.^
