Okay, so we have two triangles that are congruent to each other.
00:04
So we know that triangle d -e -f is congruent to triangle h -kl.
00:14
So if i want to find c, let's tell the c on this part.
00:22
I've got c, d, and p.
00:26
Let's start with, okay, so since h and d in the same spot, i'm going to find d.
00:30
Because 2d minus 12 is going to equal to that's angle h.
00:35
It's going to be what's in angle d, which is 58.
00:40
So we add 12 to both sides.
00:42
So 2d is equal to 60.
00:45
That'll be 70.
00:46
Divide by 2 and d is equal to 35.
00:49
Okay.
00:51
P, looks like i've got a couple options.
00:55
So i'm going to go with, oh, is that i see.
00:57
Oh, i see it.
00:59
8p minus 5 is the length of ef, which is going to match up to lk.
01:04
And that looks like that's going to be 27...
