Answer with no links, and work shown if you can. It is given that quadrilateral DEFG is inscribed in circle P. Because a circle measures 360 degrees, mEFG + mGDE = 360 degrees. By the_,1/2mEFG+1/2mGDE=180 degrees. By the inscribed angles theorem,_=1/2 mGDE and _=1/2mEFG. This means m

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.
