Hi, so we're given, this is a rhombus and this is 4x plus 2.
00:06
This is 7x minus 13 and the diagonal is 34 and we're finding 80 and you end up getting the right answer, but i'm assuming you made the video because you don't know how you actually got to that.
00:20
So let's talk about rhombi rombuses.
00:23
Okay, so romuses are basically imagine like a like a square, but you kind of tilt it to one side.
00:31
Meaning is it like square.
00:33
It used to be a square, not anymore because, well, like all four sides are equal.
00:37
So that's what kind of allows you to make like this like 4x plus 2 equals 7x minus 13.
00:45
Yeah, you end up with 5.
00:46
X does become 5.
00:48
And now what the hard part is is that if you look here, we got, imagine really what a rhombus is really four right triangles kind of put right up next to each other.
00:59
So we have a right triangle right here.
01:02
And that's really how to solve is this aed is a right triangle.
01:10
So right triangle.
01:14
And you're right that that's 17.
01:15
That's kind of how that 34 helps as it gives us a leg.
01:19
It tells us that this is 4x plus two.
01:23
And we're really solving for this...
