Question

Q. 29 In quadrilateral ABCD angle A, B, C and
D are in the ratio 1:2:3:4.The measure of the
smallest angle is...
O A2
A 28
O'B. 36
0 c. 72
O 0.27​

Answer 1

LET THE ANGLES BE X

X:2X:3X:4X=360°

(SUM OF ANGLES OF A QUADRILATERAL=360°)

10X=360°

X=360/10=36

X=36°

SMALLER ANGLE OF A QUADRILATERAL=36°
