Question

While constructing a ∆ABC with AB = 3 cm, BC = 4 cm, AC = 6 cm, ∠B = 45 and we draw a

o ∠B = 60

o

base line whose length is

a) 7 cm b) 10 cm c) 9 cm d) 13 cm​

Answer 1

Step-by-step explanation:

⟹∠BAC=180−(60+45)=75

∘

Now, to check the statement.

i)Draw a line segment XY=11cm.

ii)Make an angle equal to ∠B=60 from point X and mark L on this line.

iii)Make an angle equal to ∠C=45

∘

from point Y and mark M on this line.

iv)Bisect ∠LXYand∠MYX,let the bisectors meet at point A.

v)Make perpendicular bisector of AX,let it intersect XY at B.

vi)Make perpendicular bisector of AY,let it intersect XY at point C.

vii)Join AB & AC ,Then measure AB+BC+AC.

If that is equal to 11cm.

The statement is true and ABC is the required triangle.

Answer 2

Answer:

so dear the answer is 13cm
