3.Diketahui =BE - 160 cm

AB = 200 cm
BC=720 cm
Ditanya =CD

4.Diketahui=EC=175
BC=520
CD=140
Ditanya=Ab?

3.Diketahui =BE – 160 cm

Jawaban:

nomer 3

$frac{ab}{ac} = frac{eb}{dc} \ frac{200}{200 + 720} = frac{160}{dc} \ frac{200}{920} = frac{160}{dc} \ dc = frac{920 times 160}{200} \ dc = 736$

nomer 4

$frac{cd}{bd} = frac{ec}{ab} \ frac{140}{140 + 520} = frac{175}{ab} \ frac{140}{660} = frac{175}{ab} \ ab = frac{660 times 175}{140} = 825$
