If d .e .f .g.
00:01
Is a rhombus, and we have information for ge, that's 42, well, it's bicecter be 21 on each side.
00:08
And if d .h.
00:09
Is 16, then h .f would also be 16, and we can find gf because diagonals are perpendicular with a rhombus, using the pythagorean theorem.
00:21
You can say that gf squared, because that would be the hypotenuse, would be equal to 16 squared plus 21 squared.
00:28
16 squared plus 21 squared.
00:39
697 and so gf would be the square root of 697 if that's not how you want to put it in then you can estimate that as about 26 .4 with the same diagram if ef was 13 i'm gonna do it in green now if ef was 13 and df was 17 that would be 8 and a half on each side then find eh and this would go like 13 would be the hypotenuse equals eh squared plus 8 .5 squared.
01:49
Subtract 8 .5 squared from 13 squared.
01:55
You get 96 .75 square rooted and that's what e .h is exactly.
02:07
Or about 9 .8.
02:12
Depending on how you're rounding...
