Best ResponseYou've already chosen the best response.4What did you do for 170^2

Astrophysics

Best ResponseYou've already chosen the best response.4\[A_{\square} =a^2~~~~~A_{\triangle} = \frac{ 1 }{ 2 }bh\]

Best ResponseYou've already chosen the best response.0Oops. I got 306090 mixed up with this. I just tried using soh cah toa and got o=10 a=10 h=10^2, which doesn't make any sense. I'm not sure what to do now

Best ResponseYou've already chosen the best response.4I'm going to redraw it, dw:1438255686271:dw does this look right

Best ResponseYou've already chosen the best response.4Ok so we know that's a square and a triangle, agree?

Astrophysics

Best ResponseYou've already chosen the best response.4So for the base of the triangle we can simply do \[b = 2212 = 10\] as we know the side of the square is 12, and all the sides of the square are the same.

Best ResponseYou've already chosen the best response.4dw:1438255835677:dw so we have this now

Best ResponseYou've already chosen the best response.0It's a rectangle and a triangle

Best ResponseYou've already chosen the best response.4Well a square is a special rectangle, but if you could upload an image it would be better, but I think this is right.

Best ResponseYou've already chosen the best response.1I think it's a square.

Astrophysics

Best ResponseYou've already chosen the best response.4Yeah me to..looks like a square to me

Best ResponseYou've already chosen the best response.1Since the height is 12 and the width is 12.

Astrophysics

Best ResponseYou've already chosen the best response.4Yes, it's a square, so now you can get the total area using \[A_{total} = a^2+\frac{ 1 }{ 2 }ab\] Where a = 12 b = 10

Best ResponseYou've already chosen the best response.4I'm going to make sure though, lets just use some trig. dw:1438256489005:dw

Astrophysics

Best ResponseYou've already chosen the best response.4Yeah, so it's not a square...we can use the tan ratio \[\tan \theta = \frac{ opp }{ adj } \implies \tan \theta* adj = opp \implies \tan(45)*10 = opp = 10\]

Astrophysics

Best ResponseYou've already chosen the best response.4So this is our new drawing dw:1438256643590:dw that makes much more sense as well

Astrophysics

Best ResponseYou've already chosen the best response.4because a 45  45  90 triangle would have 10 base and 10 height

Astrophysics
 one year ago
Best ResponseYou've already chosen the best response.4So we have Area of rectangle + Area of triangle = total area

Astrophysics

Best ResponseYou've already chosen the best response.4\[A_{total} = lw+\frac{ 1 }{ 2 }bh \]

Best ResponseYou've already chosen the best response.4The original image was kind of hard to tell, maybe it's because I'm too tired :p But now you should be able to get it, just plug and chug at this stage.
