Answer:
Third option
x = 12, y = 20.78
Explanation:
This is a 30-60-90 triangle,
In such a triangle the if we are given the length of the hypotenuse, then the perpendicular or the height, which is given as x would half the length of the hypotenuse and the base given by y would be x√3
Calculate x first
x = 24/2 = 12
Looking at the four choices, only fits this value. This is the 3rd choice. So that is the correct one
If you wanted to make sure, find y = x√3 = 12√3 = 20.7846
