Answer: The correct option is (A) 5, 5√3.
Step-by-step explanation: We are given a 30-60-90 triangle, where the length of the hypotenuse is 10 units.
We are to find the length of sides s and q.
We have, using trigonometric ratios in the given right-angles triangle that
[tex]\cos 60^\circ=\dfrac{\textup{base}}{\textup{hypotenuse}}\\\\\\\Rightarrow \dfrac{1}{2}=\dfrac{s}{10}\\\\\\\Rightarrow s=\dfrac{10}{2}\\\\\\\Rightarrow s=5,[/tex]
and
[tex]\sin 60^\circ=\dfrac{\textup{perpendicular}}{\textup{hypotenuse}}\\\\\\\Rightarrow \dfrac{\sqrt3}{2}=\dfrac{q}{10}\\\\\\\Rightarrow q=\dfrac{10\sqrt3}{2}\\\\\\\Rightarrow q=5\sqrt3.[/tex]
Therefore, s = 5 units and q = 5√3 units.
Thus, the complete statement is
In the given 30-60-90 triangle, side s has a length of 5 units and side q has a length of 5√3 units.
