Question

in quadrilateral ABCD, Angle A:angle B: angle C:angle D=2:3:6:7,then the measure of the smallest angle of the quadrilateral is _____​

Answer 1

Answer:

40°

Step-by-step explanation:

From here the smallest angle is Angle A as it has the least ratio among the four angles.

Let the angles be 2x,3x,6x &7x respectively.

Then, 2x+3x+6x+7x=360

Or, 18x=360

Or, x=360/18=20

Or, 2x=20*2=40°
