Side lengths with Exact Values

Interactive practice questions

Find the length of side $h$h.

A right-angled triangle, $ABC$ , has its right angle at vertex $B$ . The other two interior angles are angle $C$ that measures $degrees(60)$ and angle $A$ that measures $degrees(30)$ . Side $interval(AB)$ that measures $\sqrt{3}$√3 units is opposite to angle $C$ and adjacent to angle $A$ . Side $interval(BC)$ that measures $h$h units is opposite to angle $A$ and adjacent to angle $C$ . Side $interval(AC)$ is the hypotenuse with a hash mark but is not labeled.
