Solution : Angle A +Angle B+Angle C=180
45+75 +Angle B=180
Angle A=180 - 120 =60
step for construction
draw BC is equal to 6.8 CM .
With B as a vertex draw angle XBC measure 75 degree.
With as a vertex draw angle YCB measure 45 degree.
Now BX and CY intersect each other at point A.
Join BA and CA
Then ABC is the required triangle
with C as centre and radius equal to BC cut an arc on both the side of AC
with A as centre and radius as before draw arcs on both side of A.C. cutting previous arc at point Aand D .
Join AD which cut A.C. at E.
Now BE is the required median.
Hope it help you.
