Answer:
75 in
Step-by-step explanation:
circumference=3.14*diameter. Plug in respective values and get 75.36, and then you round to 75.
Answer:
Cos y = t / 8
Step-by-step explanation:
Using the hints given in the question, the omitted tribagke will look like the triangle attached on the picture ;
From trigonometry :
Sin y = opposite / hypotenus
Sin y = s / 8
Opposite side = s ; hypotenus = 8
Tan y = opposite / Adjacent
Tan y = s / t
Adjacent side = t
Then ;
Cos y = Adjacent / hypotenus
Hence,
Cos y = t / 8
When you use a tens fact you round to the nearest ten and 15-8=7. The nearest ten to seven is 10
Answer:10
