Share $72 in the ratio 5:4

Step-by-step explanation:

Let ratio be x

$72=5x+4x

$72=9x

X=$72/9=$8

Required share=5×$8=$40

And 4×$8=$32

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
