The legs of a stool make an angle of `35^(@)` with the floor as shown in Fig. 5.46. Find the angles x and y.

In Fig.6.5 Find x and y.

A road crosses a railway line at an angle of 30° as shown in Fig.5.45. Find the values of a, b and c.

An inclined plane makes an angle theta_0 = 30^@ with the horizontal. A particle is projected from this plane with a speed of 5 ms^-1 at an angle of elevation beta = 30^@ with the horizontal as shown in (Fig. 5.53). (a) Find the range of the particle on the plane when it strikes the plane. (b) Find the range of the particle for beta = 120^@ . .

Find the slope of the lines which make an angle of 45^(@) with the line 3x-y+5=0
