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
