Question

The four angles in a quadrilateral are in the ratio 2:5:6:7. Find the smallest angle in the quadrilateral?

Answer 1

36

Explanation:

Quadrilateral's angels always add up to 360. Thus, 2x+5x+6x+7x=360

20x=360 (divide both sides by 20)

x = 18

To find the smallest angle, plugin x into 2x.

2(18)=36
