Question

Can someone help me pls

Answer 1

Answer:

x ≈ 16.6 units

Step-by-step explanation:

The angle between a tangent and the radius at the point of contact is 90° , so

Δ ABC is a right triangle at ∠ B

Using Pythagoras' identity in the right triangle

x² + 7² = 18²

x² + 49 = 324 ( subtract 49 from both sides )

x² = 275 ( take the square root of both sides )

x = $\sqrt{275}$ ≈ 16.6 ( to the nearest tenth )
