Answer:
x = 15
Step-by-step explanation:
The angle between a tangent and a radius at the point of contact F is 90°
Then Δ GFE is a right triangle
Using Pythagoras identity in the right triangle
x² + 8² = 17²
x² + 64 = 289 ( subtract 64 from both sides )
x² = 225 ( take the square root of both sides )
x = [tex]\sqrt{225}[/tex] = 15
