Answer: look at the photo
Step-by-step explanation:
Answer:
y = 52.02
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj/ hyp
cos y = 8/13
Take the inverse cos of each side
cos ^-1 cos y = cos ^-1 ( 8/13)
y = cos ^-1 ( 8/13)
y = 52.02012756
To the nearest hundredth
y = 52.02
