Answer: x = 12, y =
Step-by-step explanation:
A 30-60-90 triangle has sides whose lengths are related. (shown in the diagram attached) The longest side, the hypotenuse (opposite the right angle) represents 2x. The shortest side is x, and the last side is .
We know the longest side = 24 = 2x.
If the shortest side is x, that means that the shortest side = the longest side DIVIDED by 2. Therefore, shortest side = x = 24/2 = 12 .
The last side is y and equals x\sqrt{3} . We now know that x = 12. Hence, y = .

Answer:
40%
Step-by-step explanation:
In order to find percent, you can set up the fraction 2/5 to the equation x/100.
Then solve using algebra to cross-multiply.
so the answer is 40%.
In mathematics, a scale can be described in charts as a marking system at predefined times, which determines the relationship between the units that are being used and their images on the graph, and the further calculation can be defined as follows:
- Since in this question, the ratio is between 3 cm to 4 km you can make a
split, and if you are split between 3 and 4, you get the ratio between
.
Therefore the final answer is "0.75 cm to 1 km"
