Base on tangent and secant rule for intersection,
The length of WZ is 12.
The angle of the arc XZ is 39 degrees.
<h3>What is tangent of a circle</h3>
The tangent to a circle is defined as a straight line that touches the circle at a single point.
Therefore,
WX × WY = WZ²
8 × (10 + 8) = WZ²
8 × 18 = WZ²
WZ² = 144
WZ = √144
WZ = 12
74° = 1 / 2(187 - arc XZ)
74 = 93.5 - arcXZ / 2
-19.5 = - arcXZ / 2
-39 = - arcXZ
-arcXZ = 39°

Answer:
Step-by-step explanation:
- Cost of a bottle of water = 10
- Cost of pizza = 60
- Total amount = 120
- Number of water bottles = x
<u>Equation:</u>
- 10x + 60 = 120
- 10x = 120 - 60
- 10x = 60
- x = 60/10
- x = 6
