Someone explain to me how i do this law of sines problem

  44.1 cm

Step-by-step explanation:

In order to find the length of side "a", you need to know the measure of angle A. That is found by making use of the fact that the sum of angles in a triangle is 180°.

  102° + 28° + A = 180°

  A = 180° -130° = 50°

Now, you can fill in the given information in the given equation and solve for "a":

  sin(A)/a = sin(B)/b

  sin(50°)/a = sin(28°)/(27 cm)

Multiplying by a(27 cm) gives ...

  sin(50°)(27 cm) = a·sin(28°)

Dividing by the coefficient of "a", we get ...

  a = (27 cm)sin(50°)/sin(28°) ≈ 44.0563 cm

Rounded to the nearest tenth, this is ...

  a ≈ 44.1 cm

Since we're looking for a side length (not an angle), I prefer to write the Law of Sines formula "upside down" from that shown:

  a/sin(A) = b/sin(B) = c/sin(C)

Then it is one step to get to ...

  a = b·sin(A)/sin(B) . . . . . . multiply by sin(A)

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63
