Accepted Solution

A:

Answer:x = 69 and y = [tex]23\sqrt{3}[/tex]Step-by-step explanation:Firstly the hypotenuse is the side opposite the 90 degree angle. So hypotenuse is [tex]46\sqrt{3}[/tex]Since the angle given is 30 degree, with respect to this angle, the side length y is opposite and the side length x is adjacent.Now, we can use trigonometric ratios to solve for x and y. Sine is defined as [tex]sin\theta=\frac{Opposite}{Hypotenuse}[/tex] and Cos is defined as [tex]Cos\theta=\frac{Adjacent}{Hypotenuse}[/tex]Hence, we can write:[tex]Sin(30)=\frac{y}{46\sqrt{3} }\\y=46\sqrt{3}*Sin30 \\y=46\sqrt{3}*\frac{1}{2}\\y=23\sqrt{3}[/tex]Also, we can figure out:[tex]Cos(30)=\frac{x}{46\sqrt{3} }\\Cos(30)*46\sqrt{3}=x\\ x=\frac{\sqrt{3} }{2}*46\sqrt{3} \\x=\frac{46*3}{2}\\x=69[/tex]2nd answer choice is right.
