Geometry help needed asap please!!

Hello. I'm stuck on this homework problem and I'm not sure why. This seems too easy. I understand that the interior angles of the bottom triangle equal to 180 degrees, and I also believe that since the top angle is x+7, then the angle directly below (adjacent) is also x+7. For some reason, I'm not sure how to set the equation up. I don't know if 2x+14+2x+3x+1=180 is correct. Any help would be greatly appreciated!!!!!!!!!!!

Hello, and welcome to FMH!

The unlabeled angle within the triangle is equal to the labeled angle above it, so what you want is:

[MATH](x+7)+(2x)+(3x+1)=180[/MATH]

You are a lifesaver! Thank you!!!!!!

Out of curiosity you said then the angle directly below (adjacent) is also x+7 so what motivated you to double that angle.
