If they give me these length measures. dw:1365267723624:dw

They're both right triangles. I have the lengths of the sides, but I want someone to explain how I could find AB, without giving me the answer.

sorry but the side lengths are not readable :/

or were they arrows ? :)

This is a matter of using Pythagoras' theorem. a^2 + b^2 = c^2 so name your sides, and then solve for all the things you know. Even if you don't know the side lengths, you can get a formula for the length of AB.

Yeah lol and bad ones too. Do you need the length measures to help me?

I would recommend you to use similar triangles here

jazyBest ResponseYou've already chosen the best response.0
I tried the Pythagoras theorem but neither one of my triangles have 2 side lengths given. :/

If there are no side lengths given then you need to find a formula. Instead of substituting the side length for the variable, just keep the variable in there.

Sorry, my brain is completely blank today when it comes to geometry. I'm not sure what you mean.

I need to clarify is CBA right angled?

Are u sure this is only the info given ?

These aren't the ones given to me but maybe they'll work: dw:1365268927327:dw

why not try this ? dw:1365268967361:dw

AB is the only unknown

Ok, I'll try it out on paper first. One sec..

I don't know what wrong with me today :/ So I get: \[\tan(A) = \frac{ 104 }{ x} = \frac{ 186 }{ x + 98 }\]But how could I solve this with two variables?? o.o
 one year ago

RavBest ResponseYou've already chosen the best response.1
You only have one variable. A is irrelevant, all you want is x.
 one year ago

jazyBest ResponseYou've already chosen the best response.0
Oh, ok. So would I cross multiply now to solve for x?

RavBest ResponseYou've already chosen the best response.1
Yes. Please give your medals to aravind :)

jazyBest ResponseYou've already chosen the best response.0
Ok and thanks(: \[\frac{ 104 }{ x } = \frac{ 186 }{ x + 98 } \to 104(x + 98) = 186x \to 104x + 192 = 186x \to 192 = 82x \to 2.34\]

what happened @jazy ?you seem terrible on math today :/

jazyBest ResponseYou've already chosen the best response.0
@AravindG I wish I knew. . Usually I'm pretty quick to catch on, but I guess today just isn't my day for math. I'll switch subjects for a while to refresh. Thanks for the patience and help, I really do appreciate it. c:
