Applying the trigonometric ratios, the lengths of the other two sides in the right triangle are:
AC = 29.9 units
AB = 30.9 units.
<h3>What is the Trigonometric Ratios?</h3>The Trigonometric ratios used in solving any right triangle are given as:
SOH, CAH, TOA.
Apply TOA to find AC:
tan ∅ = opp/adj = BC/AC
tan 15 = 8/AC
AC = 8/tan 15
AC = 29.9 units
Apply SOH to find AB:
sin ∅ = BC/AB
sin 15 = 8/AB
AB = 8/sin 15
AB = 30.9 units.
