Tolong dong jawab yah :)

3. CD/ CA = DE/AB
24/24+X = 15/20
480 = 15.24+15X
480= 360+15X
480-360 = 15X
120 = 15X
X = 8

CA = 24 + X
CA = 24+ 8
CA = 32

4. RS / RP = ST / PQ
3/7 = X/14
42 = 7x
x = 6

[tex]3. \\ \frac{AB}{DE} = \frac{CA}{CD} \\ \frac{20}{15} = \frac{CA}{24} \\ \frac{4}{3} = \frac{CA}{24} \\ CA=32[/tex]

[tex]4. \\ \frac{RS}{RP} = \frac{ST}{PQ} \\ \frac{3}{7} = \frac{ST}{14} \\ ST=6[/tex]
