Answer:
the answer is A. 47
Step-by-step explanation:
tanθ = 15/14
the answer for 15/14 comes out to be about 1.0714 and so you put that value into your calculator using the sin^-1 button. it should look something like this sin^-1(1.0714) and press enter and you'll get 46.974 and round will result in 47
Answer:
We have to prove
sin(α+β)-sin(α-β)=2 cos α sin β
We will take the left hand side to prove it equal to right hand side
So,
=sin(α+β)-sin(α-β) Eqn 1
We will use the following identities:
sin(α+β)=sin α cos β+cos α sin β
and
sin(α-β)=sin α cos β-cos α sin β
Putting the identities in eqn 1
=sin(α+β)-sin(α-β)
=[ sin α cos β+cos α sin β ]-[sin α cos β-cos α sin β ]
=sin α cos β+cos α sin β- sinα cos β+cos α sin β
sinα cosβ will be cancelled.
=cos α sin β+ cos α sin β
=2 cos α sin β
Hence,
sin(α+β)-sin(α-β)=2 cos α sin β
Answer:
I think it is the daughter
Step-by-step explanation:
only because she is only 115 m away from home plate itself and the father is 132m away which is going to take some for the sound waves to travel and for anyone to hear . Also if you don't believe me, more of an explanation is ...
Kilometers are 1,000 times larger than meters. The meter is the base unit for measuring length or distance in the metric system.
132 km x 1,000 = 132,000m and 115 is already in meters now i think that is simple enough of an explanation. Your welcome. I know I'm right
