Hi Hikari - this looks quite tricky at first, but can you see how to calculate the angle marked in red? Hint: exterior angle of the smaller right angled triangle equals the angle marked in red plus 90 degrees.

- anonymous

hey dumbcow, can you explain guyc hint about the exterior angle?

- anonymous

I'm back

- dumbcow

ok back,
this is a 30-60-90 right triangle
so the upper angle is 60
have you learned sin and cos functions ??

- anonymous

no

- dumbcow

wait never mind,
a 30-60-90 triangle is a special triangle with ratio 1:sqrt(3):2
for our triangle 9:9sqrt(3):18
therefore
k + 3sqrt(3) = 9sqrt(3)
k = 6sqrt(3)

- anonymous

so702=6sq3

- dumbcow

k = 6sq(3)
what is 702?

- anonymous

idk why

- anonymous

i got k + 27=729

- dumbcow

how?

- anonymous

3 time 3 time 3=27
9X9X9=729

- dumbcow

a 30-60-90 triangle is a special triangle with ratio 1:sqrt(3):2
for our triangle 9:9sqrt(3):18
therefore
k + 3sqrt(3) = 9sqrt(3)
k = 6sqrt(3)
sqrt = square root
why are you multiplying 3*3*3 and 9*9*9

- anonymous

i am sorry that i got myself confuse

- dumbcow

thats alright its hard to explain without drawing it out

- anonymous

yea

- dumbcow

1:sqrt(3):2
means vertical side length is 1
bottom side length is sqrt(3)
hypotenuse or diagonal side is 2
because for our triangle the vertical side is 9
9 is our scale factor
multiply everything by 9
9:9sq3:18
bottom side is 9sq3
diagonal is 18

- anonymous

i am confuse now

- dumbcow

sorry
answer is k = 6sqrt(3)
i'll try to scan in a picture later

- anonymous

that's aok can help me with other questions
