Answer:

Step-by-step explanation:
since sin theta = 3/4, opposite length = 3 units and hypotenuse length = 4 units
by pythagoras' theorem, adjacent length = 
thus cos theta = adjacent/hypotenuse = 
I would do this by setting up a proportion:
3.5 = 4.9
20 x
now solve it by cross mulitiplying
3.5x=20*4.9
3.5x=98
x=28
The answer is 28 kilometers.
Answer: V=
cm^3
Step-by-step explanation:
V = s³
V = (0.01)³
V=(1/100)³
V=
cm^3
Answer:
The answer is C
Step-by-step explanation:
Since the answer is infinite decimal, i will round the answer to the nearest tenth, which is 81.3. i used proportion to solve this question.
