Finding 'A'

this is how to find 'A' in a right-angled triangle:




1. find your formula. in this case, it would be:
-------------->A²=C²-B².

2. substitute 'C' and 'B' with your dimentions.
-------------->A²=15²-8²
-------------->A²=(15x15)-(8x8)<------(know how to multiply with exponents? skip this)

3. calculate.
-->225-64
-->A=the square root of 161
-->A=12.68

How to find side "B" on a right angle triangle. Say that you have a right triangle with "A" being 3m. and C being 5m.









Now you have to square all of them. B2=C2-A2.







Now let's replace the sides with the dimensions. B2=62-32

That is the same as writing 36-9=B2

27=B2

Now you have to find the square root.
27 sqaured is equal to B

B=5.19
