This is a 30-60-90 triangle, which means that the triangle has angles of 30°, 60°, and 90°.
In a 30-60-90 triangle,
The hypotenuse is 2 times the length of the shortest side
And the longer leg is √3 times the length of the shortest side
____________________________________________________________
We have the length of the shortest side, 7.
This means that the longer leg (y) will be 7√3 and the hypotenuse (x) will be 2(7), or 14
Your answer is A) x = 7√3, y = 14
