anygoal [31]

Answer:

243.911, or rounding to the nearest unit, 244.

Step-by-step explanation:

For this, you need to know a concept in Trigonometry called "Law of Sines". This states that the ratio of any side of a triangle to the sine of the angle opposite is equal for all cases in that triangle.

Knowing this:

$\frac{200}{ \sin(48) } = \frac{x}{ \sin(65) } \\ x \sin(48) = 200 \sin(65) \\ x = \frac{200 \sin(65) }{ \sin(48) } \\ x = 243.911$

Answer:

1,260 mg of copper.

Step-by-step explanation:

This is because in a 3 to 1 ratio, the first number has to be 3 times the second number which is just multiplied by one. since zinc is the second number, it stays the same but the copper as to be 3 times the amount of zinc so 420 mg times 3 which equals 1,260.

Four squares are joined together to form one large square if the perimeter of one of the original squares of 8X units what is th

allsm [11]

Answer:

16 x units

Step-by-step explanation:

Perimeter of a original square= 8 x units

Perimeter of a square= 4× side

Side of a square = $\frac{perimeter}{4}$

Side of a square = $\frac{8x}{4}$

Side of a square= 2 x units

since four square are joined together to form a single square

So each side of a bigger square= 4 x units

Perimeter of a new bigger square= 4 × 4 x units

Perimeter of a new bigger square= 16 x units

Hence, the correct answer is 16 x units
