You're going to use the Pythagorean Theorem which is a²+b²=c².
1.) a and b are called legs and the missing length is called the hypotenuse. The legs are the numbers given to you, such as, 8 and 15. Plug them into the equation: 8²+15²=c².
you need to do the oppsite opporation and that the answer for example x-2=4 just add 2 and 4 and thats the answer that is aslo the same rule as divsion and multiplecation sorry for spelleng mistakes hope this helps!!!!!!
