jimthompson5910 (jim_thompson5910):

let's add the variables x and y |dw:1449639599147:dw|

jimthompson5910 (jim_thompson5910):

are you able to find the value of x?

jimthompson5910 (jim_thompson5910):

hint: pythagorean theorem

OpenStudy (anonymous):

I believe the answer is 2cm

jimthompson5910 (jim_thompson5910):

how did you get to that answer

jimthompson5910 (jim_thompson5910):

can you tell me what you got for x and y?

OpenStudy (anonymous):

Since the first triangle's base is 1, then x and y would be 1

jimthompson5910 (jim_thompson5910):

x is not 1

jimthompson5910 (jim_thompson5910):

|dw:1449639980162:dw|

OpenStudy (anonymous):

I believe 2

jimthompson5910 (jim_thompson5910):

a^2 + b^2 = c^2 1^2 + 1^2 = x^2 x = ???

OpenStudy (anonymous):

2^2 which would be 4, right? I'm sorry I'm slow at this

jimthompson5910 (jim_thompson5910):

1^2+1^2 = 2 so \[\Large x^2 = 2\] which means \[\Large x = \sqrt{2}\]
