Question
Find the area of $\triangle A B C$ in Exercise $35,$ but assume that $C$ is the reflection of $B$ across the $y$ axis.
Step 1
Since C is the reflection of B across the y-axis, and B is 5 units away from the y-axis, C will be 5 units away from the y-axis on the left side. Therefore, the coordinates of C will be (-5,0). Show more…
