Please help i need the answer​

Step-by-step explanation:

P = 3√Q

Solve for Q

First we want to get rid of the 3

Because 3 is being multiplied by the √Q we can get rid of it by dividing both sides by 3

So first step is to divide both sides by 3

P / 3 = (3√Q) / 3

simplify

P / 3 = √Q

Next we want to get rid of the square root sign. We can do this by taking the square of each side

So the next step is to square each side

(P / 3)² = √Q²

Simplify

P² / 9 = Q

And we are done!

  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.

i think it is c, not positive though
