Best ResponseYou've already chosen the best response.1(x+7)^2 + x^2= 17^2. You can solve it yourself?

Best ResponseYou've already chosen the best response.1Yes, the hypothenuse is the longest side of a right angle triangle. Unless I forgot my basic geometry.

Best ResponseYou've already chosen the best response.1thats true, but idk what it would be then?

Best ResponseYou've already chosen the best response.1yes, simplify the x+7, you will get a quadratic, either find its root by factoring or use the quadratic formula

Best ResponseYou've already chosen the best response.1it can't be a negative. I got 6. ( I did it really quickly so you,d have to check). But a measurement cannot be negatie. ever.

Best ResponseYou've already chosen the best response.1(x+7)(x+7) + x^2 = 17^2. Bring all to one side it will give you 2(x^2+14x120). One of your zero will b 20 the other will be 6

Best ResponseYou've already chosen the best response.117^2 = [x+7]^2 + x^2 289 = x^2 + 14x + 49 + x^2 2x^2 + 14x  240 = 0 divide by 2 x^2 + 7x  120 = 0 factor [x + 15][x  8] = 0

Best ResponseYou've already chosen the best response.1so opposite side = 8 adjacent side = 15

Best ResponseYou've already chosen the best response.1yes that should be it, if what I calculated is right.

Best ResponseYou've already chosen the best response.1oh wait wait, with yoru calculations you get x= 8, you have to plug it in x+7 therefore 8+7 = 15. Don't forget you had an initial equation

Best ResponseYou've already chosen the best response.1yeah x=8 because when I set x+15=0 I get a negative 15. so I plug 8 back into x+7?

Best ResponseYou've already chosen the best response.1so my opposite side is just 8? and adjacent is 15?
