The sum of interior angles in a quadrilateral is 360°. Let's call the two unknown angles "2x" and "5x".
We know that:
248° + 56° + 2x + 5x = 360°
Simplifying:
304° + 7x = 360°
Subtracting 304° from both sides:
7x = 56°
Dividing both sides by 7:
x = 8°
So the two unknown angles are:
2x = 16°
5x = 40°
A quadrilateral has two angles that measure 248° and 56°. The other two angles are in a ratio of 2:5. What are the measures of those two angles?
