Question

is x, 25 degree and Z forming a linear pair or not give reason

Answer 1

x=115°
z is forming a linear pair

Answer 2

Hi ,

From the figure ,

i ) 40° + x + 25° = 180° [ straight angle ]

=> x + 65° = 180°

x = 180° - 65°

x = 115°

ii ) z = 40° ( vertically opposite angles )

iii ) Now ,

x + 25° + z

= 115° + 25° + 40°

= 180°

Therefore ,

x , 25° , z° form a straight angle .

[ Sum of Two adjecent

angles makes 180° is

called linear pair ]

Here , we have three


angles .

I hope this helps you.
