Okay, this problem has three and one types of problems because we're finding the measure of angle c, b, and a.
00:09
I like to start with the biggest angle, so that would be me working with c.
00:13
So sideline c is the largest side.
00:18
That's how i knew that that was going to be the largest angle.
00:20
The largest side is always across from the largest angle.
00:23
And then from there, you can just plug in your other values, 1519, 15, 19.
00:29
And i'm going to go ahead and follow the directions this time and round to the nearest degree.
00:34
So angle c is 110 degrees.
00:37
So following through then, we can figure out the measure of angle b.
00:41
And if you have a calculator, that goes up and grabs that equation, it makes your life so much easier because all you have to do is swap out the 28 and the 19.
00:55
Leave the 15 alone in that problem, plus, and then 2 times 15...
