# Math Help - Determine angle x.

1. ## Determine angle x.

Please help me determine angle x. Also explain with text so I understand.

Determine angle x.

2. The angle right of 150,5 degrees, in the small triangle, would be 180-150.5=29.5. So now at the small triangle you will have 29.5+10.6+w=180 $\Rightarrow$ w=139.9.
The angle at the bottom right of the big triangle will be 139.9+y=180 $\Rightarrow$ y=40.1 .
So now you know two angles of the big triangle and it would be :
x+71.9+40.1=180 $\Rightarrow$ x=68
