Lines and Angles Worksheet

In the given figure, what value of x will make AOB a straight line?

• $50\degree$

• $40\degree$

• $45\degree$

• $55\degree$

In the given figure, $l\parallel m$ . If s and t are two transversal as shown, Find the value of x and y.

•  $x=120\degree,\ y\ =115\degree$  

•  $x=65\degree,\ y=120\degree$  

•  $x=120\degree,\ y=65\degree$  

•  $x=65\degree,\ y\ =115\degree$  

The angles between North and West and South and East are:

• Complementary

• Supplementary

• Both are acute

• Both are obtuse

In the given figure, l, m and n are parallel lines, and the lines p and q is also parallel. Find the value a, b and c.

• $20\degree,\ 40\degree,\ 30\degree$

• $30\degree,\ 40\degree,\ 50\degree$

• $20\degree,\ 30\degree,\ 40\degree$

• None of these

In the given figure, $PQ\parallel ST$ 

Then, the value of x + y is:

•  $125\degree$  

•  $135\degree$  

•  $145\degree$  

•  $120\degree$  

The supplement of the complement of an angle measuring $15\degree$ is: 

•  $75\degree$  

•  $105\degree$  

•  $15\degree$  

•  $90\degree$  

In the given figure, if $p\parallel q$ then the value of x is: 

•  $85\degree$  

•  $90\degree$  

•  $100\degree$  

•  $135\degree$
