Set up and solve an equation:
3(90-x) = (180-x). Then 270 - 3x = 180 - x, or 270 - 180 = 2x.
90 = 2x, so x = 45 deg.
Is this true? 3(90-45) = (180-45)? If so, x = 45 degrees is correct.

This is such a unique language. What language is this? I wanna try and learn it
The change is given by the difference between how much you paid and how much you actually had to pay. For example, if you pay with a $50 bill and you had to pay $13, your change will be
dollars.
In this case, we have

So, Gabriel's mistake was to leave the negative sign to the "-2" at the end of the expression, instead of flipping it to positive "+2" when subtracting it.
Heyya
I think the pattern is (n+1)^5
1=1^5
32 = 2^5
243 = 3^5
1024 = 4^5
3125 =5^5
Then the next number should be 6^5 = 7776
Hope you get it
