Question

Intr-un paralelogram ABCD avem m(< ABC)=5X m (<BAD).
Aflati masurile unghiurile paralelogramelor  .....multumesc :*

Answer 1

<ABC + <BAD = 180°
<ABC = 5 * <BAD
=> <ABC + <BAD = 5 * <BAD + <BAD = 6 * <BAD = 180°

=>  <BAD = 180 / 6 = 30°  
=>  <ABC = 5 * <BAD = 5 * 30 = 150°
Dar:
<BAD = <BCD = 30°
<ABC = <ADC = 150°
