Answer:
Radius AB = 9.3 units
Step-by-step explanation:
Given:
BC (tangent) make right angle with radius AB.
AC = 16 units
BC = 13 units
Find:
Radius AB = ?
Computation:
Using Pythagoras theorem:
[tex]Hypotenuse^2 = Perpendicular^2 +Base^2\\\\AB =\sqrt{AC^2 -BC^2}\\\\ AB =\sqrt{16^2 -13^2}\\\\AB =\sqrt{256 -169}\\\\AB =\sqrt{87}\\\\AB =9.327[/tex]
Radius AB = 9.3 units
