HELPPP please 5 stars to the correct answer

Answer 1

• 46.48 cm

----------------------

AB and AC are perpendicular since AB is tangent to circle at point A.

BC is the hypotenuse of ΔABC and it length is:

• BC = AC + 20
• BC = 44 + 20
• BC = 64

Find the length of AB using Pythagorean theorem:

• 
  `AB=√(BC^2-AC^2)`

• 
  `AB=√(64^2-44^2) =√(2160) =46.48\ rounded`
