Hello!</h2>
The answer is:
The correct option is:
D. 40 feet.
<h2>
Why?</h2>
To solve the problem and calculate the width of the river, we need to assume that the distance from A to B and the angle formed between that distance and the distance from A to the other point (C) is equal to 90°, meaning that we are working with a right triangle, also, we need to use the given angle which is equal to 34°. So, to solve the problem we can use the following trigonometric relation:

Where,
alpha is the given angle, 34°
Adjacent is the distance from A to B, which is equal to 60 feet.
Opposite is the distance from A to C which is also equal to the width of the river.
So, substituting and calculating we have:


Hence, we have that the correct option is:
D. 40 feet.
Have a nice day!
Answer:
11/15
Step-by-step explanation:
Divide both the numerator and denominator by the GCD
55 ÷ 5
75 ÷ 5
=11/15

Answer:
See below
Step-by-step explanation:
Fact: The sum of two shortest sides must be greater than the longest side.
1. 6, 10, 8; 6 + 8 = 14; 14 > 10; This is a triangle.
2. 46, 24, 21; 24 + 21 = 45; 45 < 46; This is not a triangle.
3. 23, 35, 10; 23 + 10 = 33; 33 < 35; This is not a triangle.
4. 8, 9, 17; 8 + 9 = 17; 17= 17; This is not a triangle.
The area of a circle is pi*r^2=a since we know the diameter is 24 and radius is half the diameter the r=12 so the area of the half circle = 1/2*pi*12^2 and the area of the square is simply base*height = 24*24 then the area with the missing portion must be 24*24-1/2*pi*12^2 = 576-72pi= approximately 349.8cm
