@DylanMultiProduction When she plugs in for the pythagorean theorem: h^2 + 144 = 400, subtract 144 to get h^2 = 256, now you need to get just h (instead of h^2), so you need to take the square root of both h^2 and 256 to get h=16 (because the square root of 256 is 16). Hope I didn't just confuse you!

howd u get 16?

AAAAAHHH what about a triangle with no right angles, and area has been given, 6.75cm2, and 2 lengths either side of x which i need to find, how would i do that? x is acute and the diagram is not drwan to scale, any help!!!

i hate how she always in all the videos stares at the camera at the beginning AND the end! Thanks for help though!

@d1995a3 yah i did.... but sometimes i get a little confused :P thanks for the help anyway! :D

[d1995a3]

@chellooza Well 12 squared is 144 because 12 x 12 = 144. And 20 squared is 400 because 20 x 20 = 400. Did you lean Pythagorean Theorem yet?

[chellooza]

how did she get 144 and 400? i need help and im only a 6th grader lol

She explains it well, But the way my teacher does it, Is more complicated. So i like this lady better.
