Answer:
A.
Step-by-step explanation:
Recall: SOHCAHTOA
Reference angle = θ
Side Adjacent to θ = 8
Hypotenuse = 15
Therefore, we would apply CAH since we know the hypotenuse and the adjacent length.
Thus:
Cos θ = Adj/Hyp = 8/15
Cos θ = 0.5333
θ = Cos^{-1}(0.5333)
θ = 57.7713051°
θ = 57.8° (to nearest tenth)
Answer:
Student B did the problem corectly
Step-by-step explanation:
Student a did 3*4 while student B did 3*3*3*3 which would equal 27
Answer:
8 hours total
Step-by-step explanation:
100=2
400=8
2 times 4 =8
The cube of 20 can be written as
. Split the 20 up into 2*10. Even though we are doing the cube of this value, first do
and then do
. Now multiply these numbers together so it is 8*1000=8000. Which is answer choice D. 8000
