Best ResponseYou've already chosen the best response.0They'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.

Best ResponseYou've already chosen the best response.2sorry but the side lengths are not readable :/

Best ResponseYou've already chosen the best response.1This 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.

Best ResponseYou've already chosen the best response.0Yeah lol and bad ones too. Do you need the length measures to help me?

Best ResponseYou've already chosen the best response.2I would recommend you to use similar triangles here

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

Best ResponseYou've already chosen the best response.1If 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.

Best ResponseYou've already chosen the best response.0I 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

Rav

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

jazy

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

Rav

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

Best 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:
