The question must be like:
x3/a2 + y3/b2 + z3/c2=(x+y+z)3/(a+b+c)2
**************************************************************
Let x/a=y/b=z/c=k
then x=ak,y=bk,z=ck
Now RHS=(x+y+z)3/(a+b+c)2
=(ak+bk+ck)3/(a+b+c)2
=k3(a+b+c)3/(a+b+c)2
=k3(a+b+c)
=k3a+k3b+k3c
= (x/a)3*a + (y/b)3*b + (z/c)3*c
=RHS
=x3/a2 + y3/b2 + z3/c2

inclination=45
so m=tan 45=1
c=-1(given)
so equation y=mx+c
y=1*x-1
y=x-1

Here height =50 m
base= 200m
tanθ=height/base=50/200=1/4=tan14
so angle of depression=90-14=76
