5. Find the value of x. Assume that segments that appear to be tangent are tangent.

Answer: x = 8
Step-by-step explanation:
Since 15 is the radius, and x is tangent, we know that it is a right angle
Using Pythagorean Theorem a² + b² = c²
a = x
b = 15
c = 17
17² = 15² + a²
289 = 225 + a²
a² = 64
a = 8
