Question

determinati masurile unghiurilor unui patru later convex, stiind ca acestea sunt direct proportionale cu 2,3,7 si 10

repede va rog

Answer 1

a,b,c,d-laturi patrulater convex

a,b,c,d d.p cu 2,3,7,10

a+b+c+d=360 grade

a supra 2=b supra 3=c supra 7=d supra 10

a+b+c+d supra 2+3+7+10 = 360 grade

a+b+c+d supra 22 = 360 grade

a+b+c+d = 360/22

a+b+c+d = 16.(36)

a=16.(36) x 2

a=32.(72)

b=16.(36) x 3

b=49.(09)

c=16.(36) x 7

c=114.(54)

d=16.36 x 10

d=163.(36)
