Hogy lehet ezt a matek feladatot megoldani?

a szogek:

a,b,g,d,e

CLB=60

Kiindulhatsz pl a kovetkezo egyenletekbol:

b+g = 120 (CLB ⊿)

a+b = 90 (ABC ⊿)

a+2d = 180 (KAL ⊿)

2e + (180-d)=180 (CKL ⊿)

e+g=90 (ACB szog)

(180-d-e)+b+g=180 (CLB ⊿)

2e+d+a = 180 (CAL ⊿)

b+g = 120

a+b = 90

a+2d = 180

d= 2e

e+g=90

d+e=b+g

2e+d+a = 180

d= 2e

b+g = 120

a+b = 90

a+4e = 180

e=90-g

3e=b+g

4e+a = 180

d= 2e

e=90-g

b+g = 120

a+b = 90

a+4(90-g) = 180

3(90-g)=b+g

4(90-g)+a = 180

d= 2e

e=90-g

g = 120-b

a+b = 90

a+ 180 = 4g

270-b = 4g

180+a = 4g

d= 2e

e=90-g

g = 120-b

a+b = 90

a+ 180 = 4(120-b)

270-b = 4(120-b)

d= 2e

e=90-g

g = 120-b

a+b = 90

a+ 4b = 300

b = 70

a=20

g=50

e=40

d=80
