 Well this one was simple enough, just a little algebra. It should be noted though that due to the nature of non-floating point integers, this will only work accurately for perfect squares (ie 3 4 5, 5 12 13, etc), otherwise the answer will be rounded to a whole number. For a more accurate answer, simply replace all "int" declarations with "float" declarations.code:/***********************************************************************************/ #include "math.h"               // include the Math Libraryconst int a = 3;const int h = 5;int b;void setup()                    // run once, when the sketch starts{  Serial.begin(9600);           // set up Serial library at 9600 bps  Serial.println("Lets calculate the leg of a right triangle"); //print message (with carriage return, \n)  Serial.print("a = "); //print message without carriage return  Serial.println(a);    //print the value of variable a  Serial.print("h = ");  Serial.println(h);    b = sqrt( h*h - a*a );  //a^2 + b^2 = h^2, so b = sqrt of (h^2 - a^2); this assignment sets variable b to that value    Serial.print("b = ");  Serial.println(b);}void loop()                // we need this to be here even though its empty{}/***********************************************************************************/Serial monitor output: Lets calculate the leg of a right trianglea = 3h = 5b = 4
