Question
Use the diagram below for Questions $53-58 .$ Angle measures are in degrees.Let $a=23.2, b=18.5,$ and $m \angle C=42^{\circ} .$ Find $c$ to the nearest tenth.
Step 1
We are asked to find the length of side $c$. We can use the Law of Cosines to solve for $c$. The Law of Cosines states that $c^2 = a^2 + b^2 - 2ab\cos(C)$. Show more…
