Hello, we are going to work on solution of right angle triangles.
00:14
I'm going to do a sketch of a right angle triangle in the question.
00:21
And then from there we see what is missing.
00:26
So this is given as a, this is b and this is c.
00:30
And it is further given that b is b is 16 .8 or other b is equal to 16 .8 it is also given that side b is 30 .5 and um okay a b is equals to 30 .5 so it's advisable to label on the diagram so that you are very clear which side you are looking for.
01:08
So, firstly, we are looking for the remaining angle because we already are given that this is a right angle.
01:17
So it's 90 degrees.
01:19
So if we add all these angles, we should get 180.
01:24
So it's 90 plus 116 from 90.
01:28
So this is more like a is equals to 90 minus 16 .8.
01:43
And it gives us 73 .2.
01:48
So this is 73 .2...
