homework help!!!

[red frost]

the triangles with height h and base h/2 and with height y and base (h/2 - x) are similar so you can use tan theta (trigonometric ratio) and equate

[terse quest]

i dont get it, explain please

[terse quest]

i dont understand this either

im sorryyyy

[red frost]

do you know tangent = (height/base)

apply this for both triangles as i mentioned above

[terse quest]

yea

[red frost]

for larger triangle with height h and base h/2 you get tangent equals to h/(h/2) hence tangent = 2

eqaute this with tangent of smaller triangle with height y and base (h/2 - x)

so you get y/(h/2 -x) = 2
y = 2* (h/2 -x)
y= h - 2x

[terse quest]

ohh

i got it

thank you

so much
