Question

construct a triangle abc where BC is equal to 5 cm angle b is equal to
30 degree and ac minus a b is equal to 2 cm​

Answer 1

Answer:

Construct AB=5 cm

Construct ∠BAX=30

o

From AX, cut the line segment AD which is equal to AC−BC=2.5 cm

Join the point BD

Construct a perpendicular bisector of BD which meets AX at the point C

In order to obtain the required triangle ABC join BC

Justification:

We know that C lies on BD which is the perpendicular bisector

So we get

CD=BC

We know that AD=2.5 cm

It can be written as

AC−CD=2.5 cm

So we get

AC−BC=2.5 cm
