Question

line segment ab is equal to 10 cm is divided at C in the ratio 1 is to 4 what are the lengths of AC and CB​

Answer 1

Answer:

AC = 2cm; CB = 8cm

Step-by-step explanation:

As AC and CB are in the ratio of 1:4

AC/CB = 1/4

4*AC = CB ....(Eqn 1)

Now AC + CB = AB ........(C is a point on AB)

Thus,

AC + CB = 10 ............(Given)

Using Eqn1, we get:

AC + 4*AC = 10

5*AC = 10

AC = 2

CB = 4*AC = 8 (Using Eqn 1)

AC = 2 cm

CB = 8 cm

Answer 2

Answer:

AC :CB= 1: 4

AC = (1/5) x 10

= 2 cm

CB= (4/5)x 10

= 8 cm
