Answer:
x ≈ 9.6
Step-by-step explanation:
Δ ABC is right with ∠ C = 90° ( angle between tangent and radius )
Using Pythagoras' identity in the right triangle
x² + 14² = 17²
x² + 196 = 289 ( subtract 196 from both sides )
x² = 93 ( take the square root of both sides )
x = 
≈ 9.6 ( to the nearest tenth )

Answer:
Answer is in picture
Step-by-step explanation:
Hope it is helpful....
The Area of the Rectangle = l × w
<> 10 × 8 = 80 ft²
The Area of the Semicircle = ½
The Area of a circle = ½ (πr²)
<> π = 3.14
<> r = ½ of 8 = 4 ft
<> ½(3.14 × 4) = 6.28 ft²
The Area of the figure = Area of rectangle + Area of semicircle:-
<> 80 ft² + 6.28 ft² = <u>86.28</u><u> </u><u>ft</u><u>²</u>
Therefore, The area of the figure is <u>86.28</u><u> </u><u>ft</u><u>²</u>.
