Question

In patrulaterul convex MNPQ se stie ca m(unghi M)=80 grade iar masurile unghiurilor N,P si Q sunt d.p cu nr 5,3 respectiv 6.Calculati masurile ung N,p,Q

Answer 1

N:5=P:3=Q:6=E

N:5=E=>N=5E
P:3=E=>P=3E
Q:6=E=>E=6E

M+N+P+Q=360
80+5E+3E+6E=360
14E=360-80
14E=280
E=20

N=5E=>N=100
P=3E=>P=60
Q=6E=>Q=120
