So they give you a right triangle problem.
00:03
They go ahead and tell you that angle c is the right angle, which is typically what people do.
00:09
Now this a and b kind of switch around, but i'm just writing it here.
00:13
28 .3 is angle b.
00:17
And then sideline c or the hypotenuse is 62 .4 inches.
00:24
They said inches, right? you have i in.
00:26
Okay, so the first thing i would do is identify what the measure of angle a is.
00:31
And all you have to know is that the three angles inside of a triangle add up to be 180 minus 90 minus angle b so then the measure of angle a is going to equal well you can really just do 90 minus 28 .3 and get 61 .7 degrees.
00:54
And now it's up to you now that we know both angles but what i would probably do is figure out what sine length b is first by utilizing sokatoa, and sine length b is opposite of, so that's the opposite side, and being across from the right angle is the hypotenuse.
01:18
So we're going to use sign of 28 .3 is equal to the opposite side i called b over the hypotenuse of 62 .4.
01:29
And then to solve this, probably you just have to multiply that 62 .4 over, and just kind of a heads up, make sure you that you're in degree mode in your calculator.
01:42
So i have to change my mode around to be in degrees and just type it in 62 .4 times sign of 28 .3...
