Question

In the figure value of y is : (A)10 (B) 25 (C) 20 (D) 180

Answer 1

Answer:

D

Step-by-step explanation:

let in trapezium abcd

a=x+25

b=y

c=95

d=2x+5

seg ac is parallel to seg bd

hence ab and cd are transversal

so sum of measure of interior angle =180

angle a+ angle b= 180

x+25+y=180

x+y=180-25

x+y=155

y=155-x.....1

and angle c + angle d=180

95+2x+5=180

2x+100=180

2x=180-100

2x=80

x=40

put x=40 in 1

y=155-40

y=115

x=40

and y= 115
