Me solve it i'm so lost. giving maximum points.

AEC and BED are vertical angles, which mean they are equal.

Set those two equations to equal and find those angles, then we can find AEB.

First:

3y+20 = 5y -16

Add 16 to each side:

3y+36 = 5y

Subtract 3y from each side:

36 = 2y

Divide both sides by 2: y = 36 /2

y = 18.

Now solve AEC:

3(18) +20 = 54+20 = 74

Both AEC and BED are 74 degrees.

AEB and CED asre also vertical angles and would be the same.

Subtract 74 +74 from 360 then divide by 2:

AEB = (360 - 74 - 74) / 2

AEB = 212 /2

AEB = 106 degrees

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.
