Find the measure of all the angles

Step-by-step explanation:

9x+6+5x+90°= 180°

14x+96=180

14x=180-96

14x=84

x= 84/14

x=6

so, <A=5x=5(6)=30°

<B=9x+6=9(6)+6=54+6=60°

<C = 180-(30+60)=180-90=90°

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.
