1. if base angles of a triangle are 22.5 and 112.5 , then the height is? well, i am appearing for a maths exam, for which i need to know such type of questions.

You have to measure the longer side. The longer side is h, so:
H (height) = h * sin 22.5

You can't get an exact height from the information given. You need to know one more piece of information (a side, the third angle, etc.). You can imagine that if the side connecting the two angles given is 10 cm you would get a very different answer (height) than if the side connecting the two angles is 100 cm.
If you are looking for a formula which you could plug in the third piece of information, please state so and I'll come up with one.

The third angle of the triangle is 45°. But the rest I need to calculate....it takes some time....try using the height & distance of the arithmetic/algebra....good luck

You need the length of one side, any side will do, but you need it. Then you can either use the sine or cosine rule which can easily be looked up but which I've forgotten.
By only knowing the angles, the lengths could be any size. So the height for this question could be any number you like.

It is not possible to solve this triangle with the information given.

I agree with sep_n...missing info.
