The expression that shows the length of the side AB is 8/cos60.
Adjacent side to ∠60° = 8 inches
What is the cosine of an angle?
The cosine of an angle is the ratio of the adjacent side(to that angle) to the hypotenuse of the right triangle.
So, [tex]Cos60=\frac{8}{AB}[/tex]
So, [tex]AB=\frac{8}{Cos60}[/tex]
So, the expression that shows the length of the side AB is 8/cos60.
Thus, the expression that shows the length of the side AB is 8/cos60.
