HDTV Surprise!

…were your holidays? Your school vacation? Mine was good. I surprised my family with this HDTV, which I wrapped and hung on our wall. The size of an HDTV is determined by the length of its diagonal. What size HDTV could this be? Knowing that HDTV dimensions follow a 16:9 ratio (L & W), do you think this could be an HDTV? No scale is provided, how can you make your own? Note: This task can be solved with or without the use of the Pythagorean Theorem. CCSS: 7.G.1, 7.RP.3, 8.G.7, HSG.SRT.C.8… 0, 2

Earth Day, 2017

…What’s my angle? – We’ve used a little Solar geometry to analyze and estimate the proper angle for the tilt of my Solar panels. Should I tilt the panels on my roof to more accurately aim towards the Sun? If so, at what angle should I use? Should I be able to adjust the panels to better receive low winter Sun and high summer Sun? How do I figure all of this out? 7.G.B, 8.EE.B, HSG.CO, HSG.SRT, HS.TF, HS.C, MP2… 0, 11
