Find the value of y round your answer to the nearest tenth cos y y=8/13
2 answers:
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
