Question

represent root 7.7 on number line

Answer 1

Answer: Given: An irrational number √7.7

To find: Represent it on a number line?

Solution:

Now we have to represent √7.7 on a number line, so lets consider AB = 7.7 units and BC= 1 unit.

Now following are the steps to create a diagram:

        1. Draw AB = 7.7 units and extend it to C such that BC=1 unit.

        2. Now try to find the midpoint of AC. Let the mid point be O.

        3. Now consider O as center of circle and OA be the radius, construct a semicircle which further meets at point C.

        4. Construct a perpendicular on B which further meets the semicircle at point D.

        5. Now consider B as center of circle and let BD be the radius construct an arc which meets XY at E.

And finally we have:

         BD = BE = √7.7

Answer:

             So from above steps we can represent √7.7 on a number line.

Step-by-step explanation:

Step 1=Take AB=7.7 units and extend it to C so that BC=1 unit.

Step 2=Find the midpoint of AC and name it O.

Step 3=Now O as center and OA as radius draw a semicircle meeting at C. Step 4=Now draw a perpendicular line on B meeting the semicircle at D.
