Number plates in Victoria used to have three letters followed by three digits (e. g.YAS 233). They recently changed to a non-zero digit (1 - 9) followed by two letters
then another non-zero digit followed by another two letters (e. g. 1AA 7WS). The
government claims that this will give them twice as many distinct number plates. Is
this true?

a - base

b - exponent

so,

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

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
