Angle A of triangle = 50. $B = 30$. What is C?

Step 1: Recall the Angle Sum Property of a Triangle

The sum of the interior angles of any triangle is always equal to $180^\circ$. This is a fundamental property of triangles.

Step 2: Substitute the given angle values

We are given the measures of angle $A$ as $50^\circ$ and angle $B$ as $30^\circ$. We substitute these values into the angle sum property equation.

Step 3: Simplify the equation

First, we add the known angles $50^\circ$ and $30^\circ$ together, which gives us $80^\circ$.

Step 4: Solve for angle C

To find the measure of angle $C$, we subtract the sum of angles $A$ and $B$ from $180^\circ$. This isolates $C$ and gives us its value.
