Can someone please help me out ~ASAP~.

Mathematics
1 answer:
BARSIC [14]2 years ago
5 0

Answer:

A) 2

Step-by-step explanation:

The law of sines is based on the proportionality of sides and angles in triangles. The law states that for the angles of a non-right triangle, each angle of the triangle has the same ratio of angle measure to sine value.

sin(A)/a=sin(B)/b=sin(C)/c

Substitute the known values into the law of sines to find a.

sin(60)/a=sin(60)/2

Does anyone know how he got from step 1 to step 2??????????
padilas [110]

9514 1404 393

Explanation:

Both sides of the equation are squared.

  \dfrac{x-12}{4}=\sqrt{x} \qquad\text{given}\\\\ \left(\dfrac{x-12}{4}\right)^2=x \qquad\text{square both sides}\\\\ \left(\dfrac{x}{4}-3\right)^2=x \qquad\text{divide out the fraction}\\\\ \dfrac{x^2}{4^2}-\dfrac{6}{4}x+9=x \qquad\text{$(a-b)^2=a^2-2ab+b^2$}\\\\\dfrac{x^2}{16}-\dfrac{5x}{2}+9=0 \qquad\text{subtract $x$}

I like this better without fractions, so would multiply by 16 at this point (or earlier).

  x^2 -40x +144 = 0

  (x -36)(x -4) = 0

  x = 4 or 36 . . . . . . x = 4 is extraneous

The solution is x = 36.
