I think for this series of problems the 90 degree angle should be explicitly indicated somewhere, either stated in the problem text or indicated in the image with the little square symbol. As it is we are expected to infer that it is indeed a 90-degree angle just because it looks like it (it might be 91 degrees!). Certainly not a huge deal but don't want students to develop the habit of assuming things from diagrams.

Thanks!
