A board, 77 cm long is cut into three pieces such that the second piece is twice as long as the first and the third is 7 cm longer than the second. Find the length of the shorter piece: Cm

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.

its less than 713.21 but greater than 5.2

c) blue

why do you ask > .>

3.07*10^-4

move the decimal 4 places to the left
