d1 = DB = 16 cm
d2 = CA = 6 + x(AO)
= 176
8.(6+x) = 176
6 + x =
6 + x = 22
x = 22 = 6
x = 16 cm
5. <CAD = <ACD = 35 derajat
jumlah sudut segitiga = 180 derajat
<CAD + <ACD + <CDA = 180
35 + 35 + <CDA = 180
70 + <CDA = 180
<CDA = 180 - 70
<CDA = 110 derajat
<CDB = 180 - <CDA
= 180 - 110
= 70 derajat
karena segitiga BCD adalah segitiga sama sisi, jadi semua sudutnya sama 70 derajat.
<ACB = 180 - (<CBA + <CAB)
= 180 - (70 + 35)
= 180 - 105
= 75 derajat
