Question

root 7.7 on number line construction

Answer 1

Answer:

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.

Answer 2

Answer:

now we have represent √ 7 on number line

so let's consider AB = 7.7 units BC = 1 unit
