Are these triangles congruent ? And what is the theorem ?

I will give a brainlist for the correct answer ;)

Step-by-step explanation:

They are congruent.

The line in the middle is common. The two right sides are marked as congruent. The angle enclosed by the two sides are marked as congruent.

Therefore the two figures are congruent by SAS.

the answer would be c:   ax + b = ax + c

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
