Question

Question 4 (2 points)Find the value of the variable. Round to the nearest tenth.XKyX≈y≈2557⁰M

Answer 1

since

`Sin(\theta)=(Opp)/(Hyp)`
`Sin(57)=(x)/(25)`
`25*Sin(57)=x`
`x=20.966`

rounded to the nearest tenth is

x=21.0

Now

`Cos(\theta)=(Adj)/(Hyp)`
`Cos(57)=(y)/(25)`
`25*Cos(57)=y`
`y=13.61`

rounded tothe nearest tenth

y= 13.6
