# A + b + c = 2 s

a,b,c are three positive integers and 2s = a + b+ c.If(s – a):(s –b):(s – c) = 1:7:4, then the ratio a:b:c is- "give calculation process"

## It is called "Pythagoras' Theorem" and can be written in one short equation: a 2 + b 2 = c 2. Note: c is the longest side of the triangle; a and b are the other two sides ; Definition. The longest side of the triangle is called the "hypotenuse", so the formal definition is:

This converse also appears in Euclid's Elements (Book I, Proposition 48):  "If in a triangle the square on one of the sides equals the sum of the squares on the remaining two sides of the triangle, then the angle contained by the remaining The only appropriate response I can think of is how to interpret the exponent. Any parentheses raised to the nth power means you have to re-write that expression n times and then multiply them all.
