In the triangle above, the measure of X is 41°.

What is the measure of Z?
A.
49°
B.
139°
C.
137°
D.
47°

A.

Step-by-step explanation:

Well Y is a right angle, which is 90°, and X is 41°

The total amount of angles in a triangle is 180°

180° - 90° - 41° = 49°

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

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.
