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 = = 15

Hello!
We have two probabilities we can use; we have 170/400, for our experiment, and 1/2, which is our theoretical probability.
To solve, we just multiply the two probabilities.
=0.2125≈21.3
Therefore, we have about a 21.3% chance of this event occurring.
I hope this helps!
