Answer:

  x=\dfrac{4\sqrt{3}}{3};\ y=\dfrac{8\sqrt{3}}{3}

Step-by-step explanation:

The side ratios of a 30°-60°-90° triangle are ...

  1 : √3 : 2

In your triangle, they are ...

  x : 4 : y

In order to get these values, we need to multiply the reduced ratio by 4/√3 = (4√3)/3. Then we have ...

  x : 4 : y = (4√3)/3 : 4 : (8√3)/3

and we can see that ...

  • x = (4√3)/3
  • y = (8√3)/3

When one quarter of a number is subtracted from one third of the number, the result is 7
Rzqust [24]
The number ... n
one quarter of the number ... 1/4 of n = 1/4 * n
one third of the number ... 1/3 of n = 1/3 * n
one quarter of the number is subtracted from one third of the number ... 1/3 * n - 1/4 * n
the result is 7 ... = 7

We can put it together: 
1/3 * n - 1/4 * n = 7
4/12 * n - 3/12 * n = 7
1/12 * n = 7     /*12
n = 7 * 12
n = 84

The number you are looking for is 84.
