Answer 1

@jim_thompson5910 CAN YOU HELP?

Answer 2

20/x = x/5

20*5 = x*x

x^2 = 20*5

x^2 = 100

x = ???

Answer 3

once you find x, you can find y (using the pythagorean theorem)

Answer 4

[5\sqrt{10}\]?

Answer 5

x = sqrt(100) = ??

Answer 6

X=10

Answer 7

?

Answer 8

yep, now use this to find y

Answer 9

y=5sqrt 10

Answer 10

a^2 + b^2 = c^2

10^2 + 20^2 = y^2

100 + 400 = y^2

y^2 = 500

y = sqrt(500)

y = ???

Answer 11

50 im confused

Answer 12

sqrt(500) = sqrt(100*5)


sqrt(500) = sqrt(100)*sqrt(5)


sqrt(500) = ???

Answer 13

10*5

Answer 14

sqrt(100) is what

Answer 15

10

Answer 16

so

sqrt(500) = sqrt(100*5)


sqrt(500) = sqrt(100)*sqrt(5)


sqrt(500) = 10*sqrt(5)

Answer 17

therefore

y = sqrt(500)

y = 10*sqrt(5)

Answer 18

ooo
