Question

AB is tangent to circle O. If AO=24 and BC=50, what is AB?
The diagram is not to scale.

Answer 1

The correct option is 70

Explanation:

It is a right triangle so we will use Pythagorean theorem to find AB:

We have One side = 24 and hypotenuse = 24+50 which is 74

Now apply Pythagorean theorem:

AB = √(74)²-(24)²

AB = √5476-576

AB= √4900

Take the square root of 4900.

AB= 70

Thus the correct option is 70....
