Question

ABCD patrulater convex a and unghiurile direct proportionals cu 3,4,5,6. Determination unghiurile????

Answer 1

 [tex]\frac{\hat{a}}{3}=\frac{\hat{b}}{4}=\frac{\hat{c}}{5}=\frac{\hat{d}}{6}=\frac{360^o}{18}=20^o\\ m(\hat{a})=3*20=60^o\;;\\ m(\hat{b})=4*20=80^o\;;\\ m(\hat{c})=5*20=100^o\;;\\ m(\hat{d})=6*20=120^o\;;\\[/tex]
