Take a regular hexagon.
Is x=y=z=p=q=r where x,y,z,p,q,r are exterior angles? Why?

Take a regular hexagon. What is the sum of the measures of its exterior angles x,y,z,p,q,r?

If p and q are positive integers such that p=ab^2 and q=a^3b ,where a,b are prime numbers then LCM (p,q) is

If a,b,c are in G.P and a^(1/x)=b^(1/y)=c^(1/z) then prove that x,y,z are in A.P.

A particle moves along a straight line according to x = Pt^2 + 2qt + r where x is the distance travelled in time t and p, q and r are constants. Find an expression for the acceleration of the particle.

Find the components along the xyz axes of the angular momentum I of a particle, whose position vector is r with components x_2 y_3 z and momentum is p with components px, py and pz. Show that if the particle moves only in the x-y plane the angular momentum has only a z-componenTt.

Find x+y+z

The pth, qth and rth term of a G.P. are x, y, z respectively, then prove that- x^(q-r).y^(r-p).z^(p-q)=1 .

If pth, qth and rth term of a G.P. are in G.P. then prove that p, q, r are in A.P.

If pth, qth and rth term of an A.P. are in A.P., show that p, q, r also are in A.P.
