Question

Determinati masurile unghiurilor trapezului abcd daca acestea sunt direct proportionale cu numerele 6,8,4,6. Ce fel de trapez este abcd? Va rog urgentt

Answer 1

$\frac{a}{6}$=$\frac{b}{8}$=$\frac{c}{6}$=$\frac{360}{24}$
$\frac{a}{6}$=$\frac{360}{24}$
a=(360·6):24
a=90.
$\frac{b}{8}$=$\frac{360}{24}$
b=(360·8):24
b=120.
$\frac{c}{6}$=$\frac{360}{24}$
c=(360·4):24
c=60.
$\frac{360}{24}$=$\frac{360}{24}$
d=(360:6):24
d=90.

Marchezi ca fiind cel mai bun? Te rog. ;;)
