When a triangle has angles 30°, 60°, and 90°, its side lengths are related to each other by a special ratio.
This ratio is such that the side opposite the 30°-angle is 1, the hypotenuse is 2, and the side opposite the 60°-angle is √3. This gives a ratio 1:2:√3.
Now, if we put in 7 for the side length opposite the 30°-angle, then the hypotenuse y must be 2 · 7, or 14, and the unknown leg x must be 7√3.
In sum:
![x=7 \sqrt{3}](https://tex.z-dn.net/?f=x%3D7%20%5Csqrt%7B3%7D%20)
,
![y=14](https://tex.z-dn.net/?f=y%3D14)

Answer:
6
Step-by-step explanation:
27-h=27-(21), since h is equal to 21.
27-21=6
The unit rate for liquid A is 25/18 cups of liquid per hour. The unit rate for liquid B will be 8/3 liquid cup per hour, so liquid B evaporated faster and by 23/18 liquid faster. Hope it help!
