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!
Number 5 would be D i think
Answer:
A.less than 6 but more than 20
Answer:
8 7/24
Step-by-step explanation:
These are mixed fractions first you need to convert them
4 5/8= 37/8
3 2/3= 11/3
Take LCM of 3 and 8 which 24.
Multiply 37/8 with 3= 111/24
Multiply 11/3 with 8= 88/24
Now add both fractions
111/24 +88/24 =199/24
This is an improper fraction. Divide 199 by 24 to change this into mixed fraction
8 7/24
