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:

Hope This Is Sufficient !!!!
average, petite, and tall
50 people are surveyed about favorite preference
450 pairs ordered
average = 25/50, which is half
25/50 = ?/450
so ?/450 = 1/2
450 / 2 = 225, so 225 pairs should be average length.
hoped this helped!
Answer:
Undefined
Step-by-step explanation:
It's undefined since slope is based on the x coordinate, and since it doesn't change here there is none. It's also undefined because the line is vertical. Hope this helps :)
