Question

In the figure, AB = 3 cm, AC = 5 cm, and CD = 2 cm. Find the length of BN.

Answer 1

Answer:

3x2/2=3

Let x be the length of BN

5x/2=3

x=1.2

Answer 2

Answer:

1.2 units

Step-by-step explanation:

ANB and ADC are similar figures

Similar figures have all sides in the same ratio

AB/AC = BN/CD

3/5 = BN/2

BN = 2 × 3/5

BN = 1.2
