Question

Find the value of x in simplest radical form.

Answer 1

than i see it right this is a right triangle where to find the x value you need using pythagora's theorem - do you know it ?

Answer 2

a^2+b^2=c^2

Answer 3

i just don't know how to apply it

Answer 4

right and isosceles triangle

Answer 5

so 2 45 degree angles and one 90?

Answer 6

so you know that in case of an isosceles triangle the two legs are equal length so in this case than these legs are a and b so you need calculi the c

than a and b are 10sqrt2
how you use the pythagoras theorem ?

Answer 7

so 10^2+10^2= x

Answer 8

no

the length of a side is 10sqrt2 not just 10

Answer 9

and the sum of these is equal x^2 not just x

Answer 10

I'm confused on the equation

Answer 11

(10sqrt2)^2 +(10sqrt2)^2 = x^2

right ?

Answer 12

yes how do i simply with the sqrt

Answer 13

when you squared sqrt2 how many will result ?

Answer 14

10

Answer 15

is it the square root of 10 and then squared?

Answer 16

no

(sqrt2)^2 = sqrt2 *sqrt2 = sqrt4 = sqrt(2^2) = ?

Answer 17

sqrt(4)

Answer 18

but sqrt4 = sqrt(2^2) = (2^(1/2))^2 = (2)^(2/2) = ?

Answer 19

16

Answer 20

2/2 = ?

Answer 21

2 divide 2 = ?

Answer 22

1

Answer 23

oh so just 2

Answer 24

yes sure

so sqrt4 =

exactly

Answer 25

2

Answer 26

so in this way (10sqrt2)^2 = ?

Answer 27

200?

Answer 28

= 10^2 *(sqrt2)

yes sure

Answer 29

so is that x?

Answer 30

so there are

(10sqrt2)^2 +(10sqrt2)^2 = x^2

continue it please

Answer 31

what you wrote above for (10sqrt2)^2 = ?

Answer 32

200**

Answer 33

yes 200

so there are

200 +200 = x^2

x = ?

Answer 34

400^2= 160,000?

Answer 35

there not is squared

there is sqaurroot of 400

Answer 36

so 400? in square root

Answer 37

yes

Answer 38

20

Answer 39

perfect

Answer 40
