Answer:
The line segment 7 cm long is shown below.
Step-by-step explanation:
First we draw a line line segment whose length is 7 cm long. Then we divide the line in small parts.
The length of each part is 1 cm.
Six points on the line segment divides the line in 7 equal parts and length of each part is 1 cm.
From the figure it is noticed that we have total 7 small parts and length of each part is 1 cm. So length of 7 parts is

Hence the total length of line is 7 cm.
The law of cosines states that, if
is the angle between sides b and c,

So, plugging our values, we have

This is equal to

Subtract 3y and move it to the right
X= 1 - 3Y
