Lines and Angle...

If an angle is $$60^o$$ less than two times of its supplement, then the greater angle is 

In a pair of adjacent angles, (i) vertex is always common, (ii) one arm is always common, and (iii) uncommon arms are always opposite rays 
Then 

Vertically opposite angles are always 

In figure, $$POQ$$ is a line, then $$a$$ is equal to 

In Fig., $$PQ = PR, RS = PQ$$ and $$ST || QR$$. If the exterior angle $$RPU$$ is $$140^o$$, the the measures of angle $$TSR$$ is

In the given figure, the value of $$x$$ that will make $$AOB$$ a straight line is

A pair of supplementary angles is

If an angle measures $$10^{o}$$ more than its complement, then the measure of the angle is:

A pair of complementary angles is:

If the difference of two complementary angles is $$10$$, then the smaller angle is:
