WITH ANSWER! I believe The shorter sides of an acute triangle are x cm and 2x cm. The longest side of the triangle is 15 cm. What is the smallest possible whole-number value of x?

I think you would have to do
Set up the equation.
The formula for an acute triangle is c^2 C=the longest side.
Plug it in
15^2<1x+2x^2
15^2<3x^2
15*15=225
225<3x^2
Divide by the coefficient..
225/3<3/3x^2
75 Eliminate the exponent..

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
