Question

construct a triangle lmn in which lm t= 5.6 CM Angle B equal to 40 degree and Angle M equal to 65 degree​

Answer 1

• Take MN as the base, which is 5.6 cm.

• Now from M, using a compass, construct an arc of 5 cm.

• Next from N, using the compass, construct an arc of 4.2 cm.

• The two arcs should intersect at a point.

• Name the point of intersection as L.

• From L join M and N. You will get your desired triangle.

Answer 2

Answer:

1. Draw LN=7cm.

2. With L as centre and radius =6.4cm, draw an arc at M.

3. With N as centre and radius =5.5cm, draw an arc at M.

4. Join LM, MN.

5. Hence Δ LMN is the required triangle
