what do you have so far

But instead it’s supposed to be 1/3^2 + 1/5^2 = 1/c^2
ab = sqrt 2
1/a^2+1/b^2 = 1/c^2
c^2/a^2b^2=1/c^2
c^4=a^2b^2
c^4=2
c=forth root of 2
a^2+b^2=sqr2
a^2b^2=2
Solving we get
(a+b)^2-2ab=sqr(2)
(a+b)^2=2ab+aqr(2)
(a+b)^2=2sqr(2)+sqr(2)=-sqr(2)
so the 2nd triangle will have area 1/2 (1/c )(1/b)
and (1/c)^2+(1/b)^2 = (1/a)^2

this makes me wanna die
To know our working is right Hyp should be longest side and a and b together should be equal to c squared then reverse and root the c2 value to find C, then a+b+c is in the proximity of 4

why have you set ab = 1/ab

#

this assumption is wrong

spring arrow
#

Yeah I changed. It in. The working here

#

To solid solution in text

#

But I didn’t get. The answer

#

Can you help here?

hot pulsar
#

im ngl i dont get the soln either

spring arrow
#

I got no real solutions?

#

It’s a negative

#

I’m stuckkkkkkkk

#

Can you try this one?

#

I worked through it too.

#

(a+b)^2=a^2+b^2+2ab=c^2+2ab=3ab=3sqrt(3)

#

@hot pulsar What do i do from ehre

#

Why did u write out the whole q can’t u just screenshot it

#

1/c is not the hypotenuse

#

once you choose the side lengths one of triangle the other can’t be chosen arbitrarily

#

r u still stuck on this 1 lol
