In pythagoras's theorem, generally a is the shortest side, b is the second shortest and c is the hypotenuse:

. However, there is a problem. The questions aren't actually possible without using sine, cosine, and tangent (which are mathematical ratios if you didn't know). I can help you with this but it will take time explaining.
Answer:
27 cm
Step-by-step explanation:
every side of a cube is equal to each other. the formula for volume is LxWxH, so 3*3*3=27
Answer:
(2 2) is answer of this question
Answer:
[4, -1]
Step-by-step explanation:
Using the Elimination Method:
3x + y = 11
5x - y = 21
__________
8x = 32
__ ___
8 8
x = 4 [Plug this back into both equations to get the y-coordinate of -1]; -1 = y
The <em>y</em>'s are already <em>additive</em><em> </em><em>inverses</em><em> </em>[result in 0], canceling each other out.
