help please. eh so many questions sorry

OpenStudy (anonymous):

Whats going on man?

OpenStudy (anonymous):

okay so there are two triangles

OpenStudy (anonymous):

k

OpenStudy (anonymous):

its asking to find the area of one of them.

OpenStudy (anonymous):

@iambatman i need to tawk wid uh

OpenStudy (anonymous):

>_>

OpenStudy (anonymous):

fan me :@

OpenStudy (anonymous):

the smallest triangle kjl and 12 cm and hcm so they dont give me a number for h

OpenStudy (anonymous):

SO the smallest triangle is sides K, G, L which sides is 12cm?

OpenStudy (anonymous):

f) first use 9/18 = h/12 and then use the area 1/2 (12h) g) 9/18=h/12 and then use area=12h h)9/18=12/h and then use area= 1/2(12h) j)9/18=12/h and then use area = 12h

OpenStudy (anonymous):

so its looking for the area of jkl. and 12cm is on the bottom part of the triangle

OpenStudy (anonymous):

and the bigger triangles is 9cm and 18 cm

OpenStudy (anonymous):

|dw:1392599480619:dw|

OpenStudy (anonymous):

not to be a pest or anyting but do you know how to solve it or should i just move on?

OpenStudy (anonymous):

Oh you got this one. Area = Base times Height divided by 2

OpenStudy (anonymous):

So s,r,t A=81

OpenStudy (anonymous):

thank you so much, sorry fo being a pest :)

OpenStudy (anonymous):

9*18=162/2=81

OpenStudy (anonymous):

not being a pest, i had to run out for a minute to the store and my ride couldn't wait

OpenStudy (anonymous):

f) first use 9/18 = h/12 and then use the area 1/2 (12h) g) 9/18=h/12 and then use area=12h h)9/18=12/h and then use area= 1/2(12h) j)9/18=12/h and then use area = 12h these are the answer choices

OpenStudy (anonymous):

i don't see what they are wanting for some reason. I can solve for the first one because I have both base and height, but I don't have both on the second one.

OpenStudy (anonymous):

alright its fine. ill try to solve it

OpenStudy (anonymous):

i think H

OpenStudy (anonymous):

Your forumlas for triangles are \[A=\frac{ b * h }{ 2 }\] or\[ A=\frac{ 1 }{ 2 } *b*h\]

OpenStudy (anonymous):

ya my teacher last year told me that but everything has been cleared from my brain. so h is pretty much correct?
