Question

......
If A-B-C, 1(AC) = 7 cm, 1(BC) = 4 cm then, I(AB) =
(a) 11 cm (b) 3 cm
(c) 9 cm
(d) None​

Answer 1

Answer:

9cm

Step-by-step explanation:

Iam not sure about this answer

Answer 2

Answer:

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
