Question

construct triangle ABC,where base BC=7.2 cm, angle b=75 degree and AB+AC=9.5cm​

Answer 1

Answer:

Correct option is

C

AB = 6.1 cm: AC = 5.1 cm

Step 1 : Draw a line segment BC of length 7cm

Step 2 : Draw an angle of 45

o

from point B

Step 3 : From Ray AX cut off the line segment BD=1cm

Step 4 : Join C to D

Step 5 : Draw side bisector of DC

Step 6 : Extend side bisector of DC it intersect the Ray BX at point A

Step 7 : Join A to C, ABC is the required triangle.

On measuring, AB=6.1cm,AC=5.1cm
