Question
Three of the angles in a quadrilateral measure 342°, 2°, and 4°. What is the measure of the fourth angle?
Solution
The sum of the angles in a quadrilateral is 360°.
First, add up the three given angles: 342° + 2° + 4° = 348°.
Then, subtract this sum from 360° to find the measure of the fourth angle: 360° - 348° = 12°.
So, the measure of the fourth angle is 12°.
