360 - 27 - 56 - 80 = ?
To find the measure of the fourth angle in a quadrilateral, you need to know that the sum of the angles in any quadrilateral is always 360 degrees.
Let's calculate it step by step:
1. Add the given angles together:
27 + 56 + 80 = 163
2. Subtract the sum from 360 to find the measure of the fourth angle:
360 - 163 = 197
Therefore, the fourth angle in the quadrilateral measures 197 degrees.
