Hey, sweets you got this, or do you want help?

sweetburger · Answer

Ok in a 45 45 90 triangle you have sides that always follow a particular rule.|dw:1469770271753:dw|
in the case of this problem a=1. So to find the length of the hypotenuse just substitute a for 1.

Your input is welcome either way jade :).

Kay, @CamPayne Sean is walking you through the smart version. I can teach you the way-easy dumbed down version as well, that will always work with finding hypotenuse' or legs of a right triangle

campayne · Answer

i mean i get what y'all are getting at, im just not sure how to get the answer

jadeishere · Answer

|dw:1469770499043:dw|
a= 1
b = 1

1^2 + 1^2 = c^2
1 + 1 = c^2
2 = c^2
sq rt of 2
