Projectile Motion

Hey,

I was teaching myself projectile and have gotten a bit confused. When is it that the angle found needs to be left negative, or the positive value needs to be taken?

Eg in question 4d attached, the angle of -8 degrees must be absolute valued, to be +8.

However in question 2cii attached, the negative value is kept as negative.

Slightly confused.

Thanks heaps in advance!
