- 2 sudut tumpul lainnya yg tersisa = 180-60 = 120˚
b) misal: p.sisi sejajar 1 (p1) = 2n
p.sisi sejajar 2 (p2) = 5n
maka:
L.trapesium = 1/2 . (p1+p2).t
80 = 1/2 . (2n+5n).8
80 = 4.7n
80 = 28n -----> n = 80/28
n = 2,86
jadi, p1 = 2n = 2.2,86 = 5,72 cm
p2 = 5n = 5.2,86 = 14,3 cm
c) K.trapesium = 5,72+14,3+10+10 = 40,02 cm
5. a) sudut MSP = 90˚-45˚ = 45˚
sudut RNQ = sudut siku2 = 90˚
b) MN = SR = 26 cm
c) PM = QN = (PQ-SR):2
= (48-26):2
= 22:2
= 11 cm
maaf cm it aj yg bs kjwab..
