Answer:

the opposite positive number is negative, and the opposite to a negative number is positive.

Step-by-step explanation:

In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite number, sign change, and negation.

The measure of two complementary angles have a ratio of 3:2. What is the measure of the larger angle?
azamat

Answer:

54 degrees

Step-by-step explanation:

Complementary angles add to 90 degrees

3:2

Multiply each by x

3x:2x

Add the angles together and set equal to 90

3x+2x = 90

Combine like terms

5x= 90

Divide each side by 5

5x/5 = 90/x

x =18

The angles are 3x = 3(18) =54

   and 2x = 2(18) = 36
