Answer:
5
Step-by-step explanation:
In a 30-60-90 triangle, the side opposite the 30 degree angle (x) is equal to n, the side opposite the 60 degree angle (y) is equal to n[tex]\sqrt{3}[/tex], and the hypotenuse (10) is equal to 2n
knowing this, set 10 = 2n
n = 5
since we want to find x, the side opposite the 30 degree angle, this is equal to n = 5
x = 5
