Best ResponseYou've already chosen the best response.0I have every confidence in @nincompoop and I like the approach, of course a + y =180 (straight angle). good starting point.

Best ResponseYou've already chosen the best response.0Hi @ yomambf, basically what you do is start from what you know. What they are saying is, you know that the sum of the angles in a straight angle is 180 degrees (i.e. a + y)

Best ResponseYou've already chosen the best response.0Are you listening a + y = 180 degrees ( a straight angle [ i.e. angle of 180 degrees])

Best ResponseYou've already chosen the best response.3dw:1439576026035:dw you were given these equations: \[b'=180(x+10)(y+5) \\ b'=180x10y5 \\ b'=(180105)(x+y) \\ \text{ recall we also have } x+y=90\]

anonymous

Best ResponseYou've already chosen the best response.0All that @freckles said was if b + b' = 180 and the sum of all the angles in the triangle equals 180 degrees then b' + (x + 10) + (y+5) must equal 180 degrees

Best ResponseYou've already chosen the best response.3this is where I was going: dw:1439576736012:dw \[b'=180(x+10)(y+5) \\ b'=180x10y5 \\ b'=(180105)(x+y) \\ \text{ recall we also have } x+y=90\] \[b'=16590 \\ b'=75 \\ \text{ now realize } \\ y+a=b+b' \\ y+a=b+75 \\ \text{ then solve for } a \\ a=by+75\]

Best ResponseYou've already chosen the best response.1The simplest exposition (minus all the details), would be a+y = 180 b + b' = 180 so a+y = b+b' we want to solve for a, then it follows a = b+b' y the rest of the details can be plugged in from the information of the other triangle containing b'

Best ResponseYou've already chosen the best response.1whatever rule it is, can be figured out without any prior knowledge of it.
