The given question is:
A right-angled triangle has a hypotenuse of length 10 cm, and one of its acute angles measures $30^\circ$. What are the lengths of the other two sides?
Let's solve this step-by-step.
<h2>Given Information:</h2>In a right-angled triangle, the relationship between the sides and angles is governed by trigonometric ratios. For a triangle with one angle measuring $30^\circ$, we can deduce the following using known properties of $30^\circ-60^\circ-90^\circ$ triangles:
Let's denote the side opposite the $30^\circ$ angle as \(a\) and the side opposite the $60^\circ$ angle as \(b\). Given the properties mentioned earlier, we have:
<div class="formula"> \[ a = \frac{c}{2} \] \[ b = a \cdot \sqrt{3} \] </div>Substituting the given hypotenuse \(c = 10 \text{ cm}\), we get:
<div class="formula"> \[ a = \frac{10}{2} = 5 \text{ cm} \] \[ b = 5 \cdot \sqrt{3} = 5\sqrt{3} \text{ cm} \] </div> <h2>Conclusion:</h2>The lengths of the other two sides, considering one angle measures $30^\circ$, are:
Therefore, the correct choice among the given options is:
$5 \text{ cm and } 5\sqrt{3} \text{ cm}$.
