Question

Two angles of a quadrilateral measure 180° and 100°. The other two angles are in a ratio of 3:5. What are the measures of those two angles?

Answer 1

Answer:

There are 360° in a quadrilateral. 160° are accounted for (130+30), so the other two angles must sum to 200°. The ratio 3:7 means that one angle must represent 30% of the remaining 200° while the other angle represents 70%. Multiplying 200*0.3= 60° and 200*0.7= 140°. These are the measures of the remaining angles
