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:
x=18
Step-by-step explanation:
Hey There!
So if you did not know all of the angles in a triangle will add up to equal 180
So we use the equation
180=2x+3x+5x
and solve for x
step 1 combine like terms
2x+3x=5x
5x+5x=10x
so now we have
180=10x
step 2 divide each side by 10
180/10=18
therefore x = 18
hope this helps and if you have any more questions feel free to ask :)
Answer: Simple, it got Translated according to the rule (x, y) → (x + 2, y + 8) and reflected across the y-axis
Step-by-step explanation:
Answer:
117 feet squared
Step-by-step explanation:
Multiply the height (9 feet) by the width (13 feet).
9 x 13 = 117
117 feet squared
Note: squared is added when describing area (it's used as an exponent in numbers)
1, 3, 5 are functions because they pass the vertical line test
