Answer: 116.2°</h3>
Work Shown:

The first equation is one of the three variations for the Law of Cosines.
Make sure your calculator is in degree mode.
If $600=6 tons
$600=6*2000
$600=12,000
12000/$600=$20
It’s $20 per pound
When multiplying variables with exponents, all you have to do is to add the exponents and that’s the ‘product.’
So;
(3y^10)(2y^2) is equal to (3)(2)(y^10+2).
6y^12/8y^5
When dividing exponents, you do the opposite and subtract the exponents. And you divide the whole number by half.
6y^12/8y^5 = 3y^7/4
