Answer:

8

Step-by-step explanation:

using the formula,

sin A = opp/hyp

where opp = CB = 4

hyp = AB = x

and A = 30

sin 30 = 4/x

0.5 = 4/x

x = 4/ 0.5 = 8

sin(30°) = 4/x. Multiply both sides by x.

x * sin(30°) = 4. Divide each side by sin(30°).

x = 4/sin(30°). Solve for x.

x = 8.

mote1985 [20]

Answer

Find out the how much fertilizer will Timothy need for two fields, one that is 22.5 acres and one that is 38.25 acres .

To proof

As given

Timothy is putting fertilizer on a field after planting some crops

The directions on the barrel state to use 0.75 quarts for each acre of land.

fertilizer will Timothy need for 22.5 acres = 22.5 × 0.75

                                                                     = 16.875 quarts

fertilizer will Timothy need for 38.25 acres = 38.25×0.75

                                                                       = 28.6875 quarts

total fetilizer Timothy need for two fields = 16.875 +  28.6875

                                                                   = 45.5625

                                                                   = 45.6 ( approx )quarts

Therefore the total  fertilizer will Timothy need for two fields be  45.6 ( approx )quarts .

Hence proved
