persentasenya=
a/100 x 2000 = 500
2000a = 50000
a = 25%
5) 4x+x+8x+24 derajat = 180 derajat
13x= 180-24
13x= 156
x= 12 derajat
EOC = 24+ 8(12) = 120 derajat
6) 180 derajat- 150 derajat= 30 derajat
jangan lupa jadikan jawaban terbaik yaa semoga membantu
jual per batang 2500
2.500 x 30= 75.000
untung 75.000-60.000= 15.000
keuntugan dalam persen (15.000/60.000)x100%=15%
5.4x+24+8x+x=180
13x=180-24
13x=156
x=12
jadi besar eoc = 24+8(12)= 24 + 96= 120
6. aed = 50derajad
aed+edb+dce=180
50+100+dce=180
dce=180-150
dce=30
