Answer 1

Answer:

measure of angle ADB will be 90°

if BN is 5cm then BC will be 5*2 =10 cm as median of a triangle divides it into two equal parts

Answer 2

Answer:

I) given : BD is perpendicular to AC

implies BD and AC intersect with 90 degree

so, angle ADB=90 degree

ii) given : AN is median to BC

implies N is mid point of BC (BN=NC)

BC=BN+NC = 5+5=10
