​

Answer 1

Answer:

Mark point B which represents number 4 on the number line.

Construct AB of unit length perpendicular to OB.

Taking O as centre and OA as radius. Draw an arc intersecting number line at X.

X is represented as √17.

Similarly extend A to X same as diatance AB.

Join OX where OX = √18 = 3√2.
