Hypotenuse formula Study guides, Class notes & Summaries

WHEN YOU SEE: -An Isocleles Triangle with a hypotenuse that doesn't have the √2 next to it -How do you do that quick equation ex: ISO triangle : Hypotenuse = 16 - Answer--Divide the hypotenuse by 2 and multiple by √2 . ex: 16 = 16/2 = 8*√2 = 8√2 When you see: -An abstract sequence question -such as... ex: if the terms of sequence t1,t2,t3,...tn, what is the value of n? 1. The sum of the n terms is 3,124 2. The average (arithmetic mean) of the n terms is 4 - Answer--Thin...
