Answer:
Step-by-step explanation:
This is an equation for which you need to solve for the value of the missing angle beta.

sin(15) has a decimal answer that you will find on your calculator. Finding that value makes this equation then
cosβ = .2588190451
Now use the 2nd button and then the cos button to find the angle that has a cos of that decimal. When you hit 2nd then cos, you should see this on your screen:
cos⁻¹ (
After that open parenthesis, enter you decimal then hit the enter button to find the angle. You should get 75, which is Choice B.

Answer:
y=-2 x=-2
Step-by-step explanation:
y=-x-4
y=x
you can plug y in for x in the first equation by using substitution
y=-y-4
and then you solve for y
2y=-4
y=-2
so y equals -2. Since y=x, x also equals -2. Therefore
y=-2 x=-2
Cos x=5/12. Solve for x which is 65.37 degrees.
Volume of space inside shop is 288 m³
<u>Given that;</u>
Dimensions of rectangle = 8 meter , 12 meter , 3 meter
<u>Find:</u>
Volume of space inside shop
<u>Computation:</u>
Volume of rectangle = [l][b][h]
Volume of rectangle = Volume of space inside shop
So,
Volume of space inside shop = [8][12][3]
Volume of space inside shop = [96][3]
Volume of space inside shop = 288 m³
