If a line makes angle 90 degree and 60 degree respectively with the positive direction of X andY axis find the angle which makes with the posotive direction of Z axis
as we know cos^2alpha+cos^2 beta+cos^2 gamma=1 then put the value of alpha as 90 ,beta as 60 and solve this equation then you will find the angle gamma made by the Z axis

Yo bro
If a line makes angle 90 degree and 60 degree respectively with the positive direction of X andY axis find the angle which makes with the posotive direction of Z axis
30degree by using cosine property
as we know cos^2alpha+cos^2 beta+cos^2 gamma=1 then put the value of alpha as 90 ,beta as 60 and solve this equation then you will find the angle gamma made by the Z axis
