Kayla is working on a new snowboard trick. Her best trick used to be a 360, degrees full-circle turn, but now she can turn further by an additional 180, degrees half-circle.

What is the angle measure of her total turn now?

Her total turn is 360 degrees (her best trick) + 180 degrees (additional turn) = <<360+180=540>>540 degrees. Answer: \boxed{540}.

So, it's 540 degrees?

Yes, her total turn is 540 degrees.

To find the angle measure of Kayla's total turn, we need to add her previous best trick (360 degrees) to her additional turn (180 degrees).

360 degrees + 180 degrees = 540 degrees

Therefore, the angle measure of Kayla's total turn now is 540 degrees.
