Lines and Angle...

If the straight lines AB and XY  intersect at the point O and $$\angle AOX=3 \angle XOB$$, then the four angles formed at O are:

Find the angle which is $$60^o$$ more than its complement.

In figure, if $$l \parallel m$$, then the value of $$x$$ is:

Two supplementary angles differ by $$48^o$$. Then find these angles.

Angles forming a linear pair can both be acute angles.

Find the angle which is $$80^o$$ more than its complement.

How many pairs of adjacent angles, in all, can you name in figure?

If two adjacent angles are equal, then each angle measures $$90^o$$.

If $$AB\parallel CD$$ and $$BC\parallel DE$$, then the find the value of $$x$$.

In the figure measure of two angles are given. If line ED $$\parallel$$ seg AB and  E-C-D then find the values of $$x$$ in degrees.
