Question

Ques) Find x and y,if AB and CD are parallel.​

Answer 1

Answer:

x=30, y=40

Step-by-step explanation:

2x+10 = 2y-10 [alternate angles]

=> 2y-2x=20

=> 2(y-x)= 20

=> y = 10+x

now,

(x-5)+(2y-10)+(x+y+15)=180 [angle sum property of triangle]

=>2x+3y=180

=> 2x+3(10+x) = 180 [putting y=10+x]

=> 5x+30=180

=> x = 30

now,

y = 10+x

y = 10+30 [putting x = 30]

y= 40
