In figure, ABCD is a quadrilateral with ZD= 55° and angle B=104^ c . If Z BAD and ZBCD are in the ratio 2:3. The values of 21 and 2 are respectively:​

Answer»

Answer:

X = 104° and Y = 55°

Let angle BAD be 2X and BCD be 3x

As BAD:BCD = 2:3

=> 2x+3x=360-104-56 ( ALL ANGLES OF A QUADRILATERAL SUMS TO 360 )

5x=200

x=40°

BAD=2x=80°

BCD=3x=120°

X=180-BAD=180-80 X=100°

Y=180-BCD=180-120 Y=60°
