What is the arc measure of abc in degrees?

Hello from MrBillDoesMath!

283  degrees

Discussion:

A circle has 360 diverges so summing up all the angles gives:

360 =  (7y - 7) + (20y-11) + (4y + 6)     => combine like terms

360 = (7y + 20y + 4y) + (-7 - 11 + 6)    =>

360 = 31y - 12                                       => add 12 to both sides

372 = 31y                                              =>

y = 372/31 = 12                                

measure arc ABC =

360 -  measure arc (7y-7) =

360 - (7*12-7) =

360 - (77) = 283

Thank you,

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.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
