You simply have to put cos-1(sin(25))
Answer:2 3/5
Step-by-step explanation:
So if we are increasing a number, we are increasing its percentage value. The normal percentage value for an item is 100% or 1. We can take 3% and turn it into a decimal.
3% is the same as 0.03 as a decimal. The next step is to add 0.03+1 .00 to get 1.03. We have to always add the 1.00 whenever we are increasing the value. I’ll give you a reason why, let’s say you want to buy a skateboard and there are no sales so that you can get it for cheaper. The price will always be 1.00% no matter what.
So lastly we have to multiply 1.03 by 10
Which will give us 10.30

The order of operations, is PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction) so you should always follow that order when you're solving equations like this one, but when it comes to multiplication and division, it just depends on whichever one comes first, and the same is true for addition and subtraction. So since there aren't any parentheses or exponents here, we will start with multiplication or division...it just depends on which one comes first in the equation. 15 ÷ 3 is first so we start with that: 15 ÷ 3 = 5:
5 + 6 x 2 - 10 = ? Now we move onto the next multiplication or division problem we see until there are no more left. 6 x 2 is the next and last one:
6 x 2 = 12 5 + 12 - 10 = ? Now we move on to addition and subtraction, and again, whatever comes first is what we do first:
5 + 12 = 17 17 - 10 = ? Last but not least: 17 - 10 = 7
So your answer is 7! Hope this was helpful!
