Given a triangle with side PQ=8 cm. To get a line PQ’=3/4 of PQ, we divide  the line segment PQ in the ratio​

3:4

Step-by-step explanation:

Given -

Length of line PQ = 8 cm

In order to get a line PQ’=3/4 of PQ, we first need to divide the line PQ into four equal parts and each of these parts would be of equal lengths i.e 8cm/4 = 2 cm

Now out of these 4 parts, three are to be taken to form line PQ'

So length of PQ' = 3*2 cm = 6 cm

Ration should be 6:8 = 3:4

idk

step-by-step explanation:

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
