Answer 2

Answer:

solutions:

Explanation:

Let us draw a rought figure.

seg

BC = 7 cm. AC > AB.

We can draw ray BT such that

Z TBC = 40°

Point A is on ray BT. Take point D on

opposite ray of ray BT such that

BD = 3 cm.

Now AD = AB + BD = AB + 3 = AC

(:: AC – AB = 3 cm.)

.. AD= AC

.. point A is on the perpendicular

bisector of seg CD.
