Question

Draw a line segment of length 12 cm and divide it in the ratio 5 : 7. Measure the two parts
​

Answer 1

Answer:

Given: Length of line segment 7.6 cm and ratio 5 : 8 i.e., m : n.

Step-by-step Construction:

Step 1: Draw a line segment AB of length 7.6 cm.

Step 2: Draw any ray AX, making an acute angle with AB.

Step 3: Locate 13 ( = m + n ) points  on AX so that

Step 4: Join

Step 5: Through the point  ( m = 5 ) , draw a line parallel to  ( by making an angle equal to  )  at  intersecting AB at the point C.

So, we get

⇒ AC : CB = 5 : 8

⇒ AC = 2.9 cm  and CB = 4.7 cm

Answer 2

Step-by-step explanation:

let the two parts be 5x and 7x

5x+7x = 12

12x = 12

x= 1

5x = 5

7x = 7

the measure of two parts= 5cm and 7cm
