Use the trig ratio which
gives you the most information. Here we have opposite and hypotenuse
relative to angle x, so think sin( x ) = 14.1 / 27.9<span>Now we want to solve for x, but x is stuck inside the sine function
So how do we do this?
We can 'undo' the sine function by using the inverse sine. apply the inverse Sin to both sides of the equation.
sin^-1 ( sin(x) ) = sin^-1 ( 14.1 / 27.9)
the left side 'cancels' , leaving you with x
x = sin^-1 ( 14.1 / 27.9)</span><span>Now you need a calculator.
Make sure you are in degree mode.
Calculators can give you answer in radian or degree.
If you get a decimal answer, you are probably in radian mode.
Round up if you want nearest hundredth
30.3563 ≈ 30.36
Round up again if you want nearest tenth
30.36 ≈ 30.4
Hope this helps! :)

90 because a Triangle is 180° and that is a 90° angle so that means the orher angle add is 90
Answer:
x=39, y = 5 and z = -4.
Step-by-step explanation:
x + y - 5z = 24
y + z = 1
z = -4
Plug z = -4 into the second equation:
y + -4 = 1
y = 5.
Now plug x = -4 and y = 5 into the first equation:
x + 5 - 5*4 = 24
x = 24 - 5 + 20
x = 39.
5(32+26)=x. All 5 albums have 32 football cards and 26 baseball cards. You need to find out how many cards each album has individually, then multiply that number by 5, and get your final answer.
Answer:
A. The distribution is symmetric, so use the mean and standard deviation.
mean: 8, standard deviation: 3,1
Step-by-step explanation:
This looks symmetric, considering that the values look proportionate.
