How to Find Missing Sides and Angles of a Right Triangle? (+FREE Worksheet!)
Missing Sides and Angles of a Right Triangle – Example 1: Find AC in the following triangle. Round answers to the nearest tenth. Solution: \(sin\) \(θ=\frac{opposite}{hypotenuse}\). \(sin\) \(45^\circ=\frac{AC}{8}→8 ×sin 45^\circ=AC\),now use a calculator to find \(sin\) \(45^\circ\). \(sin\) \(45^\circ=\frac{\sqrt{2}}{2}→\cong 0.70710\) AC\(=\) \( 0.70710 \) \(×\) \( 8 \) \( \cong 5.7 \) → AC\(=5.7\) The […]
