Question

In the given figure ,L//m. if s and t be transversal such that s is not parallel to t find the value of x and y

Answer 1

let us consider angle w°
w= 65°...................(corresponding angle)..(¡)
y°+w°=180°.............(linear pair of angles)
y°+65°=180°..........(from ¡)
y°=180°-65°
y°=115°
let us consider angle z°
z=50°.................(vertically opposite angle)...(¡¡)
z°+x°=180°...............(interior angles)
50°+x°=180°
x°=180°-50°
x°=130°

Answer 2

Answer:

let the angle be w°

w°=65°(corresponding angle)

y°+w°=180°(linear pair of angle)

y°+65°=180°(from j)

y=115°

let the angle be z

z=5°(vertically opposite angle)

z°+x°=180°(interior angle)

50°+x=180°

x=180°-50°

x=130°

Hope this help you
