We're given a triangle.
00:03
We're told that it is a right angle triangle.
00:07
And then we're told, sorry, that angle c is the right angle.
00:10
And it tells us that this side, little b, is 8 .3.
00:15
And the angle b is 17 .2.
00:19
And that's all we're told.
00:20
And we have to find everything else.
00:21
So the easiest thing to find is angle a because it's just 90 minus angle b.
00:27
So we're just going to take 90 minus 17 .2.
00:31
And that gives me 72 .8.
00:33
So that's that angle and that's that part done.
00:37
Then i need to find another side.
00:38
It really doesn't matter which side i look for, but i'm going to look for a little c.
00:43
So little c, i'm going to find by saying that sign of b is, sorry, it's not sign of b.
00:49
I'm going to actually fill it in at 17 .2...
