2x -20 -1 =0
2x -21=0
2x=21
x= 10.5
Well it would be 200 × 8 which would equal to 1600
A. Hydrogen and oxygen are classified as elements.
Explanation: they are from the periodic table (which is a table of elements) and it wouldn’t make sense for them to be minerals, energy or organisms. They aren’t living things.
<h3>
Answer: 30.78181 meters</h3>
The value is approximate. Round that however you need to.
========================================================
Explanation:
- lowercase a = side opposite angle uppercase A
- lowercase b = side opposite angle uppercase B
- b = AC
Using the law of sines, we can say:
a/sin(A) = b/sin(B)
45/sin(30) = b/sin(20)
b/sin(20) = 45/sin(30)
b = sin(20)*45/sin(30)
b = 30.78181 approximately
You'll need to make sure your calculator is in degree mode.
