A line makes an angel theta with each of the x-and z-axes. If the angel beta, which it makes with the y-axis, is such that sin^2beta=3sin^2theta ,then cos^2theta equals a. 2/3 b. 1/5 c. 3/5 d. 2/5

A line makes the same angle theta with X-axis and Z-axis. If the angle beta , which it makes with Y-axis, is such that sin^2(beta)=3sin^2theta , then the value of cos^(2)theta is

A line makes an angle theta with the x-axis and the y-axis. If it makes an angle alpha with the z - axis such that sin^(2)alpha= 3sin^(2)theta , then cos ^(2)theta is equal to
