Use the information to solve the triangle. Round your answers to two decimal places. Hint: draw a sketch first to determine if you should use Law of Sines or Cosines. C=123°, a=41, b=57

c = 86.5 (3 sig. fig)

A = 23.4° (3 sig. fig.)

B = 33.6

Step-by-step explanation:

Using cos Law,

c = √(57² + 41² - 2(57)(41)cos(123))

c = 86.5 (3 sig. fig)

Using sin Law,

sinA/41 = sin123/86.5

A = 23.4° or 157° (rejected) [C is 123°, if A is 157, it violates the angle sum of triangle]

Using angle sum of triangle,

B = 180 - 23.4 - 123 = 33.6

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.
