Answer:
The angle Rick must kick the ball to score is an angle between the lines BX and BZY which is less than or equal to 32°
Step-by-step explanation:
The given measures of the of the angle formed by the tangent to the given circle at X and the secant passing through the circle at Z and Y are;
![m\widehat{XZ} = 58^{\circ}](https://tex.z-dn.net/?f=m%5Cwidehat%7BXZ%7D%20%20%3D%2058%5E%7B%5Ccirc%7D)
![m\widehat{XY} = 122^{\circ}](https://tex.z-dn.net/?f=m%5Cwidehat%7BXY%7D%20%20%3D%20122%5E%7B%5Ccirc%7D)
The direction Rick must kick the ball to score is therefore, between the lines BX and BXY
The angle between the lines BX and BXY = ∠XBZ = ∠XBY
The goal is an angle between ![m\widehat{XY}](https://tex.z-dn.net/?f=m%5Cwidehat%7BXY%7D)
Let 'θ' represent the angle Rick must kick the ball to score
Therefore the angle Rick must kick the ball to score is an angle less than or equal to ∠XBZ = ∠XBY
By the Angle Outside the Circle Theorem, we have;
The angle formed outside the circle = (1/2) × The difference of the arcs intercepted by the tangent and the secant
![\therefore \angle XBZ = \dfrac{1}{2} \times \left (m\widehat{XY} -m\widehat{XZ} \right)](https://tex.z-dn.net/?f=%5Ctherefore%20%5Cangle%20XBZ%20%3D%20%5Cdfrac%7B1%7D%7B2%7D%20%5Ctimes%20%5Cleft%20%28m%5Cwidehat%7BXY%7D%20%20-m%5Cwidehat%7BXZ%7D%20%5Cright%29)
We get;
∠XBZ = (1/2) × (122° - 58°) = 32°
The angle Rick must kick the ball to score, θ = ∠XBZ ≤ 32°
