So the right triangle.
00:08
The first one is finally the side opposite to the given angle, around the two decimal places.
00:16
So if you're talking about the side opposite that angle, there would be your side.
00:22
And so from that angle, you're talking about the opposite and adjacent sides.
00:26
So your tangent function is opposite over adjacent.
00:38
And so if you did tangent of pi over 6 is equal to x, over 75 .3.
00:50
And all you have to do is take and plug into your calculator.
00:55
Make sure your calculator is in radiance.
01:00
Tangit of piver 6 times 75 .3.
01:16
Tangitaphira 6 and 7 .57, etc.
01:26
So i'm getting here, x is equal to 43 .474 would be the next number, so that would not round.
01:41
That's the two decimal places.
01:42
And then the next one says, find the length of the hypotenuse.
01:52
For the high length of the hypotenuse, remember a squared plus b squared equals c squared for a right triangle.
02:00
Let's see you can do 75 .3 squared plus 43 .47 squared equal c squared...
