1. Given two angles of a triangle, find the measure of the third angle: $65^{\circ}$ and $50^{\circ}$. answer: degrees

Step 1 ：Given two angles of a triangle, find the measure of the third angle: $65^{\circ}$ and $50^{\circ}$.

Step 2 ：The sum of the angles in a triangle is always $180^{\circ}$. So, to find the third angle, we can subtract the sum of the two given angles from $180^{\circ}$.

Step 3 ：third_angle = 180 - 65 - 50

Step 4 ：Final Answer: The measure of the third angle is \(\boxed{65^{\circ}}\)
