In notebook..​

Answer 1

AB=7.6 units

BC=1 unit

Step 1=Take AB=7.6 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.

Step 5=Now B as center and BD as radius draw an arc meeting XY at E.

Now, BD=BE=√7.6
