Question

10. In the given figure, AB and CD are two straight lines which intersect
each other at O. If COE = 75°, find the values of x, y and u.​

Answer 1

Answer:

Solution:-

x+y=180-75=105

x+u=180

then,

x=70;y=35,u=110

proof,

x+y+75+x+u=360

2x+y+u=285

140+35+110=285

Answer 2

Answer:

x+y=180-75

=105

x+u=180

then,

x=70

y=35

u=110
