Answer:
y = 8·√3
Explanation:
From the drawing of the right triangle, we have;
The length of the opposite leg to the given 60° (reference) angle = 12
The length of the adjacent leg to given 60° (reference) angle = x
The length of the hypotenuse side = y
By trigonometric ratios, we have;

Therefore, we have;

From the value of sin(60°), we have;


y = 8·√3
