We may assume a triangle a, b, c in general.
00:06
Let's say this is a, b, c.
00:08
So the capital a, b, and c, which are in the uppercase, represent the angle.
00:13
Where is the side which are opposite to that angle, let's say this is angle a.
00:17
So side opposite to the angle a is small a.
00:20
Similarly, side opposite to the angle b is small b.
00:26
And side opposite to the angle c is small.
00:30
We are given some majors.
00:32
Angle c is 95 degree though it doesn't look like 95 but we can assume that okay so this is 95 degree right now it's not to the scale angle b is 60 degree so the very first thing we can do we can by default get the angle a according to the angle some property that is angle a plus b plus c just add up to 180 degree so that we substitute the values we get p as 60 here and c is 95 we simplify this.
01:05
It's going to be 155.
01:08
We subtract 155 at both the sides.
01:15
Okay, we subtract it.
01:19
This got canceled.
01:20
We get the measures of a to b 25 degree.
01:24
Once we got this, let us now write that as well.
01:28
Now we have to solve this triangle.
01:30
Solving the triangle means getting each and every missing side and angle.
01:34
So one of the missing angle we already figured out.
01:37
It's angle a, so it's one of the answer right now.
01:39
This is the one of the answer.
01:42
Angle a we've got right now.
01:44
Sorry, yeah, that's angle a.
01:45
Now we have, okay, one more thing is given.
01:48
C means it's small c, basically.
01:51
So that is a side only.
01:53
This is five.
01:54
It's given to you as five units.
01:56
We have to figure out two more sites, a and b.
01:59
We can apply either of either sign rule or cosine rule.
02:02
Both of them are applicable in this question.
02:05
Let's apply sign rule...
