A. 1/S'=1/F-1/S =1/5-1/6 =1/30 =30cm b. S'/S=h'/h 30/6=h'/3 6h'=90 h'=30cm c M=S'/s 30/6 =5X

A. s' = s f / (s-f) = 6 10 / (6 - 10) = 60/-4 = -15 cm b. h' = s' h / s = 15 3 / 6 = 7,5 cm c. M = s' / s = -15/6 = -2,5 kali d. maya tegak diperbesar
=1/5-1/6
=1/30
=30cm
b. S'/S=h'/h
30/6=h'/3
6h'=90
h'=30cm
c M=S'/s
30/6
=5X
b. h' = s' h / s = 15 3 / 6 = 7,5 cm
c. M = s' / s = -15/6 = -2,5 kali
d. maya tegak diperbesar
Semoga membantu :)
