Find the value of each variable given that the hypotenuse (h) equals 143.

Answer:
D)
x = 21
y = 7√3
Step-by-step explanation:
One of the sides is 21 (clue from the provided answers).
Using the Pythagorean theorem:
(14√3)² = 21² + side²
588 = 441 + side²
side² = 147
side = 7√3
Now we have our three sides but, which one is x and which one is y?
try x = 21:
cos 30 = 21/(14√3)
0.8660 = 21/(14√3)
0.8660(14√3) = 21, yes, then x = 21
