Question

Raportul a doua unghiuri complementare este $\frac{1}{5}$.Aflati masurile celor doua unghiuri.

Answer 1

p/q=1/5=>q=5p; p+q=90; 6p=90; p=15; q=75

Answer 2

$\frac{a}{b}= \frac{1}{5} \\ \\ b=5a \\ \\ a+b=90 \\ \\ a+5a=90 \\ \\ 6a=90 \\ \\ \\ a=15 \\ \\ b=5a=75 \\ \\ a=15;b=75$
verificare
$\\ a+b=90 \\ 15+75=90 \\ 90=90$
