In this problem, we have to find the value of the angle adc, which is right here using the given information.
00:08
So in order to use the law of science to solve this problem, we need to first know the value of the side across from this angle, which is right here, 8.
00:17
And we also need the value of an angle in the side across from it in this larger triangle that is a, b, d, which is right here.
00:26
This 60 degree angle, and we know the value across from that is 10.
00:30
Notice that we don't actually use this side right here, the side from a to c.
00:36
And that is because this angle is not within this smaller triangle.
00:39
So we actually only need to look at the larger triangle from a, b, and d.
00:44
So i'll just redraw a smaller version here real quick to make this a little clear.
00:49
So we want to find this angle right here, adb, adc...
