Answer:

solutions

Step-by-step explanation:

Solution : 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.

Construction of triangle ABC.

Step-by-step explanation:

This is a question that consists of the construction of a triangle.

Information we are provided with: BC=7 cm, ∠B=40°, and AC-AB=3 cm

Step 1: Draw a 7-cm-long line segment BC.

Step 2: Draw a 45-degree angle from point B.

Step 3: Cut the line segment BD=1cm from Ray AX.

Step 4: Join C to D.

Step 5: Draw the DC's side bisector.

Step 6: At point A, the extended side bisector of DC intersects the Ray BX.

Step 7: Join A and C to form the needed triangle, ABC.

Hence, the triangle ABC is made. Refer to the figure for more information.
