Question

Express root 10.5 on the number line​

Answer 1

Answer:

Draw a line A to B of 10. 5and the extent it to 1 cm. Then give a mid point and draw a semicircle.. Then draw a line perpendicular to AB at B and intersect at D. BD is equal to root 10.5..

Step-by-step explanation:

Step 1: draw a line and mark a point A on it.

Step 2:Mark a point B on the line such that AB=10.5

Step 3:from the point B mark a distance of 1 units and mark the new point as C.

Step 4: find the mid point of AC and mark the point as O.

Step 5:draw a circle with center O and radius OC.

Step 6: draw a line perpendicular to AC passing through B and intersecting the semi circle at D. Length BD is equal to root over 10.5
