Answer:

x=14

y=7

Step-by-step explanation:

this is a 30-60-90 triangle -- u can tell bc there is a right angle marker (90 degrees) and one angle is 30, so the other angle is 60

in a 30-60-90 triangle,,

the long leg = x√3

short leg = x

hypotenuse (the side opposite the right angle marker) = 2x

since u know the long leg is 7√3, the short leg = 7

and since the hypotenuse is 2x (twice the short leg), 7 times 2 = 14
