Evidence for the work

Mark's annual income is 45000$

=> Mark's net monthly pay: M  = 45000/12 = 3750$

2.

The percentage of each expenditure per month:

Rent: (850/3750) x 100 = 23%

Food: (300/3750) x 100 = 8%

Car insurance and gas: (190/3750) x 100 = 5%

Entertainment: (760/3750) x 100 = 20%

Clothes: (150/3750) x 100 = 4%

3.

Mark's top monthly expenditure includes renting(23%) and entertainment (20%).

He should cut costs to these to be able to save more money each month.

Hope this helps!

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
