Answer:
58 ft
Step-by-step explanation:
So I attached a diagram that illustrates the triangle that is formed. We know an angle, as well as the hypotenuse. We are looking for the height, or in other words the opposite side of the angle. There is a trigonometric function defined as:
. Using this we can plug in known values and solve for the opposite side, which I'll simply represent as x.

Multiply both sides by 80

Calculate sin(46) using a calculator (make sure it's in degree mode)

Simplify

Round this to the nearest foot

Answer:
Actual width = 5 feet.
Step-by-step explanation:
The ratio of 1.2 to 1 equals the ratio of length to width.
1.2 / 1 = 6 / w where w is the actual width.
1.2w = 6
w = 6/1.2
w = 5.
Answer: x=3
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
- Multiply both sides of the equation by 3:

- Now you must make the equation equal to zero as following:

- Factor it, as you can see below. Therefore, you obtain the following result:
