Answer:
sin 90
Step-by-step explanation:
cos (0)
Using the unit circle, we know that cos 0=1
sin 1 and cos 1 are not equal to 1
sin 90 =1
tan 90 = sin 90/ cos 90 = 1/0 =undefined
Answer
w=7.6
x=43.7
Step-by-step explanation:
To solve for w you can use Sin(x)=
which would basically be Sin(50)=
then solve. Multiply the ten on both sides so you have 10*Sin(50)=w and your final answer is 7.6
To solve for x you can also use Sin(x)=
then just use Inverse of Sin^-1
The answer is x=43.7
Step-by-step explanation:
To solve this system of equations, let's first add the equations together:
There are no values of 
that will make this equation true, so the lines never intersect, and therefore there are no solutions to this system of equations.

Step-by-step explanation:
Answer:
The volume of the box is 3/4 cubic meters.
Step-by-step explanation:
We know that volume = length * width * height. We have length, width, and height already, so all we have to do is multiply.
5/6 * 1 1/8 * 4/5. First we convert 1 1/8 from a mixed fraction, to give us 9/8, as 8/8 = 1.
5/6 * 9/8 * 4/5. 5 * 9 = 45, and 6 * 8 = 48. 45/48 reduces to 15/16.
15/16 * 4/5. 15 * 4 = 60, and 16 * 5 = 80. 60/80 reduces to 6/8, which reduces to 3/4.
