20
There are a few ways to define "opposite." It could be -20 or 1/20. The absolute value of 20 is 20.
When you calculate (-20) plus (+8) by finding 20-8 and taking the opposite of the result, you are essentially using the concept of adding a negative number. By subtracting 8 from 20, you get 12. Taking the opposite of 12 gives you -12, which is the same as adding -12 to -20. This method follows the rules of arithmetic and helps simplify the calculation by converting it into a subtraction problem.

The side opposite the 35° angle is [ 20 sin(35) ] = 11.472 (rounded)
They're not. They are additive inverses. The word "opposite" has no meaning in mathematics or logic. If you think of zero as a datum, then 20 and -20 are each 20 units in "opposite" directions on a number line. That's what additive inverse means: if you add them together, you get zero which is an additive identity.
a decagon i believe has either 5 or 20 opposite sides * * * * * A decagon has 10 sides so I cannot see how it could have 20 opposite sides. It has 5 pairs of opposite sides but this does not mean that these opposite sides face each other. In an irregular decagon it is quite possible for opposite sides to be at right angles or at any angle to each other.

I can think of more than one possible answer: The additive inverse of 20 is -20 The multiplicative inverse of 20 is 1/20 or 0.05
the opposite of x or -x or -1x
On most boards, the 14 is opposite the 10. However, regional variants may exist.
here's how u do it:go backwards!!!!and when u go backwards u just do the opposite of wat u did to get the answer16 - 2 = 14 (- is opposite of +)14 x 10 = 140 (x is opposite of /)140 / 7 = 20 (/ is opposite of x)x=20
