2x+3x:180
5x:180
X:180/5
X:36
Hence angle A =2x:2*36:72
Angle D=3x:3*36:108
4y+5y:180
9y:180
y:180/9
y:20
Hence angle B=4y:4*20:80
Angle C:5y:5*20:100
Hope it helps u
Pls mark me as brainliest
And thank me also
And if u can follow me also !!

Answer:
a: d is 2:3 is = 2x , 3x sum is 180
2x+3x =180
5x = 180
transporting
x = 180/5
x = 36
a = 2(36)= 72
d = 3(36) =108
b:c is 4:5 is = 4y,5y sum is 180
4y+5y= 180
9y = 180
transporting
y = 180/9
y = 20
b = 4(20) = 80
c = 5(20) = 100
plz mark me as BRAINLIST
