8/13 = 0.6153

y = cos-1(0.6153)

y = 52.0

I'm not totally sure if this is what you mean or if this is.

y = cos(8/13) = 0.9999 which to the nearest tenth is 1.0

Answer:

52.0

Step-by-step explanation:

To solve this, we will perform the inverse cosine:

cos y = 8/13

cos⁻¹(cos y) = cos⁻¹(8/13)

y = 52.0
