Find the inverse of addition and inverse of multiplication of the following given number. a 2/5
b -5/7
c 22/7
d 12/7
e -11/8​

3x^3-x^2+6x-9

your answer is d 2,500

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
