Answer:
The Pythagorean theorem is
a^2 + b^2 = c^2
where a and b are the lengths of the legs (the sides that form the right angle), and c is the length of the hypotenuse (the side opposite the right angle.)
Answer:
25
Step-by-step explanation:
AB is a tangent to the circle hence the angle ABO is a right angle !!! With that knowledge we can construct a right-angled triangle with sides AB ,BO and OA .
Applying the Pythagorean theorem we get that OA is the hypotenuse and thus

First, subtract 68 from 57. Which equals 11. Then add 11 + 69. That equals 80.
