Question

construct a ABC in which BC =5.3CM, LB =45° LA=75 °​

Answer 1

Step-by-step explanation:

Draw a line segment AB of length 5.8cm.

2. Draw a line segment BX, sufficiently large such that ∠ABX=60

∘

.

3. From the segment BX, cut off line segment BD of length 8.4cm.

4. Join AD.

5. Draw the perpendicular bisector of AD and let it meet BD at C.

6. Join AC.

Then ABC is the required triangle.

Answer 2

Step-by-step explanation:

☛Draw a line segment AB of length 5.8cm.

☛ Draw a line segment BX, sufficiently large such that ∠ABX=60

☛ From the segment BX, cut off line segment BD of length 8.4cm.

☛ Join AD.

☛ Draw the perpendicular bisector of AD and let it meet BD at C.

☛ Join AC.

∴Then ABC is the required triangleΔ.
