Calculating Hypotenuse Using Trigonometry

Medium Additional Topics In Math Trigonometry

In a right triangle, angle $A$ measures 30 degrees, and side $a$, which is opposite to angle $A$, has a length of 5 units. Calculate the length of the hypotenuse $c$ of the triangle.

Use your knowledge of trigonometric ratios to solve for $c$. Recall the sine function relates the opposite side to the hypotenuse in a right triangle. The sine of an angle is defined as:

$$ ext{sin}(A) =\frac{ ext{opposite}}{ ext{hypotenuse}} $$
