For question number 34, first we're going to start by drawing a sketch to understand things better.
00:07
So let's see.
00:08
Here we're going to consider it as the ground level with this specific line.
00:15
And the line that the airplane itself is flying, we're going to consider it as this.
00:23
So let's say, for example, airplane is at this specific point.
00:26
We're going to name it as point c.
00:29
So we have one point that is actually a and the other one that is b.
00:34
So if we add this together, it's going to be like this, and the other one is this.
00:40
So we know that angle here is equal to 32 degree, and angle here is equal to 48 degree, and the distance between a and b is actually equal to five units.
00:49
So now that we have sketched a very good graph to understand everything better, let's find out some of the elements that are missing.
00:56
The first thing that is going to be useful later on is actually the angle cab.
01:03
In order to find angle cab and the other one is actually to find abc, we're going to use the fact that this specific line that the airplane is flying in and the line of the ground, they are parallel to each other.
01:17
So both ac and c b, they're cutting these two parallel line.
01:21
So what it means that is actually, it means that the angle c, a, b is actually equal to the measure of the angle a, c, let's say, for example, here is going to be d, and here is going to be e.
01:36
So basically, we have acd.
01:39
So we know that both of them are going to be equal to 32 degree by the question...
