Answer 2

Answer:

Construct a line segment BC = 4.8cm

Considering B as centre and any radius, construct an arc which intersects BC at point P

Considering P as centre and same radius, construct an arc which intersects the previous arc at the point Q

Considering Q as centre and same radius, construct an arc which intersects the arc in step 2 at the point R

Considering R and Q as centres and radius more than half of RQ, construct arcs intersecting each other at the point S Join BS which intersects the arc in step 2 at the point G so ∠SBC = 90o

Considering P as centre and radius more than half of PG, construct an arc Considering G as centre and same radius,

construct an arc which intersects the previous arc at the point X Join B and extend it so ∠B = 45o Draw ∠TCB = 90o

Considering M and H as centres and radius more than half of MH,

construct arcs which intersect each other at point Y Join CY and extend it so ∠C = 75o BX and CY intersects at point A after extending So, △ ABC is the required triangle .

Therefore angle  60.
