Question

Point O is the center of the circle. What is the value of x? 27 24 20 15

Answer 1

x = 24

Explanation:

Pythagorean Theorem: a² + b² = c²

Whenever a line is tangent to a circle, it creates a perpendicular bisector with the radius. Therefore, we can use Pythagorean Theorem:

PO = (18 + 7) = 25

x² + 7² = 25²

x² = 576

x = 24
