Answer 2

Step-by-step explanation:

☘Answer:-

Given:-

• AB + BC + AC = 12 cm,
• ∠B = 45⁰ and
• ∠C = 60⁰.

To find:-

• Δ ABC is the required triangle.

Solution:-

Step :- 1

• Draw a line segment XY of 12cm.

Step :- 2

• Draw ∠DXY = ∠B = 45°

and

• ∠EYX = ∠C = 60°

Step :- 3

• Draw the angle bisectors of angles of DXY and EYX which intersects each other at A.

Step :- 4

• Draw the perpendicular of AX and AY which intersect XY at B and C respectively.

Step :- 5

Join AB and AC

Therefore,

✪ Δ ABC is the required triangle.
