Okay, let's go ahead and draw out these triangles.
00:03
That way we have a visual to go off of.
00:07
We have triangle pqr.
00:10
It's a 90 degree angle, and it says that this angle right here is 56, right? and we've got that second triangle.
00:20
It's also 90 degrees here.
00:22
And it says that this side right here is 34 degrees.
00:30
And it's labeled y, z, x.
00:33
Okay? now, something that we need to remember is all the triangle, when you add up the angles together, it should equal 180 degrees.
00:43
So i just want to find out what angle r is.
00:46
All right? so we know that this is 90.
00:50
We know that angle p is 56.
00:53
We don't know what angle r is, so i'm just going to write r.
00:56
But we do know if we add them all together, we will get 180 degrees.
01:00
So i could just solve for r, right? 90 plus 56 is going to give you 146 plus r equals 180, and then you could subtract 146 from 180, and that would give you r equals 34...
