Answer 1

so just use pythagora

13^2 = x^2 +(5sqrt2)^2

x = ?

Answer 2

12.60952021

Answer 3

easy please

step by step

169 = x^2 +25*2

169 -50 = x^2

119 = x^2

x = sqrt119

Answer 4

yes ?

Answer 5

how you have got 12.6 when 12*12 = 144

Answer 6

Hmm, I got sqrt 159

Answer 7

how ?

5sqrt2 *5sqrt2 = not equal 5*2

Answer 8

is equal 25*2

Answer 9

ok. ?

Answer 10

why ? you dont know pythagora alone ?

Answer 11

hypothenusa squared equal one side squared + second side squared

yes ?

Answer 12

hypothenusa here is 13 in than will be 13*13=169

and the other side is x and what you know is 5sqrt2 so than

5sqrt2 *5sqrt2 = 25*2 = 50

ok. ?

Answer 13

alright

Answer 14

from these result that x^2 = 169 -50 = 119

x=sqrt119

yes ?

Answer 15

Yes, sorry. Many of the helpers are showing me different methods.

Answer 16

but in this case hope that you believe me - yes ,

Answer 17
