In this question, we are given a right triangle, and we are given that the angle a equals to 68 .2 degrees, and the side c equals to 23.
00:13
So side c is here.
00:15
And we are asked to find the side a, and they're also asked to find the angle c.
00:22
First of all, we know that the angle b equals to 90 degrees, because it's a right triangle.
00:28
And in the right triangle, the sum of the other two angles, that is a plus c, must be equal to 90 degrees.
00:39
And since we know that c, a equals to 68 .2, we're going to get 68 .2 plus c equals to 90.
00:53
And therefore, after subtracting 68 .2 from both sides, we are going to get c equals to 90 minus 68 .2.
01:03
And this equals to 21 .8 degrees.
01:11
So the angle c is 21 .8 degrees...
