Question

Two angles of a quadrilateral measure 60° and 160°. The other two angles are in a ratio of 3:11. What are the measures of those two angles?

Answer 1

Answer:

30  and 110 degrees

Step-by-step explanation:

The angles sum to 360 degrees

  you have   60 + 160 = 220    leaving   140 more in a ratio  3:11

     one is   3 / (3+11) = 3/14      3/14 * 140 = 30    the other is 110
