Given:
A figure of a right triangle.
To find:
The missing side by using the trigonometric ratios.
Solution:
In a right angle triangle,

In triangle ABC,



Multiply both sides by 270.



Therefore, the missing side length is b=231.4 inches.

Answer:
y = 5.595090517 or approximately 5.6
Step-by-step explanation:
Tan47 = 6/y
y x Tan47/Tan47 = 6/Tan47
y = 5.595090517 or approximately 5.6
The rise from the ground by the skateboard is 5.5 inches
<h3>How to determine the height above the ground?</h3>
The length of the skateboard is given as:
Length (l) = 18 inches
The angle of elevation (x) is
x = 17∘
Represent the height with h.
The value of h is calculated using the following tangent ratio:
tan(x) = h/l
Make h the subject
h = l * tan(x)
Substitute known values
h = 18 * tan(17)
Evaluate
h = 5.5
Hence, the rise from the ground by the skateboard is 5.5 inches

Answer:
432 liters
Step-by-step explanation:
Because the container was already 4/9 full, 240 liters is 5/9 of the whole.
1. Convert 5/9 to a decimal and then a percent by dividing the fraction and then multiplying by 100:
5/9 = 0.5556 = 55.56%
2. To determine what number 240 is 55.56% of, write the equation like this:
0.5556x = 240
(In which x = the number you are solving for)
3. Divide both sides of the equation by 0.5556 to isolate the variable.
x = 
x = 432 (Don't forget the unit, liters)
4. To check your work, make sure that 240 is 5/9 (55.56%) of 432:
432 × 0.5556 = 240
(Note: Because the fraction converts to a repeating decimal, I had to round it. This means the answer is a very small decimal off from the actual answer that I put.)
