Question

determinati unghiurile unui patrulater convex stiind ca acestea sunt direct proporţionale cu 2,4,6,8​

Answer 1

Răspuns:

{<A,<B,<C,<D} d.p {2,4,6,8}

<A/2=<B/4=<C/6=<D=8=K=> <A=2K

<B=4K

<C=6K

<D=8K

<A+<B+<C+<D=360⁰

2k+4k+6k+8k=360⁰

20k=360⁰/20=>k=18⁰

<A=18×2=36⁰

<B=18×4=72⁰

<C=18×6=104⁰

<D=18×8=144⁰
