@mrdee I am sorry! XD Every time you come on in the recent few days, you have a lot of math on the Time line! XD
-
@metaltao and I just got done reviewing multiplying improper fractions with mixed numbers at school:(
-
@mrdee have you learned about Sig Figs yet?
-
@mrdee well whenever you get into sciences and or physics you'll need em'
-
@rednorth I didnt calculate the answer, but now you only need to replace the values. Sorry, but i wrote that with a touchpad http://rainbowdash.net/attachment/819030
-
@mastermushi s'cool
-
@mastermushi thx
-
@mastermushi I wrote you could use the syn law to find cd, i meant you can you the syn law to find X, sorry
-
@mastermushi Mushi, you're great at math but I think you're over-thinking this.
-
@northernnarwhal well, that is how i'd do it
-
@mastermushi Which is fine, just that you can solve it in under a minute in just 2 equations if you really wanted to.
-
@rednorth see that i made a small mistake there, you use the second Syn law to find X, not C. C you find by pytagoras after using the first syn law
-
@mastermushi although i don't believ is nessecary to square the equation at any point...
-
@rednorth I think my more basic math is getting rusty, my highschool was totallyuseless, so i mostly rememebr the college math
-
@mastermushi i'm redoing my highschool trig cuz my proff is an arse
-
@mastermushi Since both triangles are right angled the primary trigonometric ratios can be applied to them. First, apply the primary cos ratio to the 59° and the 3.4m to find the length of the middle line connecting the two triangles. Second, use the primary cos ratio again with the length of the middle line and the 42° to find the length of x. It's very basic substitution when you actually work it out.
-
@northernnarwhal oooh, cos. yeah, there is that too. When i saw the problem i noticed there were 2 angles and one side and went straight to the syn law
-
@northernnarwhal i forgot to mention that the center line is actually that long, it's not just my poor drawing skills
-
@mastermushi Yeah, right angled triangles are incredibly easy to solve.
-
@northernnarwhal this is true
-
@northernnarwhal yeah thats almost right its 6.8m
-
@northernnarwhal my calculator when i applied tan and such to resolve X gave me 6.7563402.... let me recalc
-
@northernnarwhal for the other triangle yes but im solving in the fewest steps possible
