Question

ABCD is a trapezium if AB ll CD angle a = 74 degree and Angle B : angle C =4:5. find the measure of angles D,B and C

Answer 1

in trapezium angle A=angle B
so angle B=74

now angle C=(74*5)/4=92.50
now angle D=360-(74+74+92.5)=119.50

so B=74, D=119.50, C=92.50

Answer 2

this is the solution
