Lines and Angle...

Two angles are called adjacent if

At $$4:15$$, the angle formed between the two hands of a clock is:

$$\angle ABC$$ in the following figure is a / an:

The complement of $$(90^o-a)$$ is :

In Fig, POQ is a line. The value of x is:

If the sum of two adjacent angles is $$100^{\circ}$$ and one of them is $$35^{\circ}$$, then the other is :

Find the complement of the angle :

Find the angle which is $$20^o$$ more than its supplement.

Find the angle which is $$30^o$$ more than its complement.

If the sides of a triangle are produced, then the sum of the exterior angle i.e. $$\angle a+\angle b+\angle c$$ is equal to:
