Question

Two angles of a quadrilateral measure 133⁰ and 188°. The other two angles are in a ratio of

6:7. What are the measures of those two angles?

Answer 1

18 and 21

Explanation:

We take those two angles as 6x and 7x

133⁰ + 188° + 6x + 7x = 360(Sum of angles of a quadrilateral)

321+13x=360

13x=360-321

13x=39

x=39/13

x=3

6x=6x3=18

7x=7x3=21
