Question

A quadrilateral has two angles that measure 190° and 10°. The other two angles are in a ratio of 3:5. What are the measures of those two angles?

Answer 1

60 degrees and 100 degrees

Explanation:

360 - (190 + 10) = sum of other two angles

360 - 200 = 160

160/(3+5) = 160/8 = 20

20 × 3 = 60 degrees, 20 × 5 = 100 degrees
