Answer:

The 4th option.

Step-by-step explanation:

Rational numbers are numbers which can be expressed as a fraction. Irrational numbers are numbers which can't be expressed as a fraction. Square root 16 is a perfect square so it is a rational number.

Please help!! Double points! write the ratios for sin X and cos X (Image attached)
Orlov [11]

Answer:

The ratio for sin(X) is \frac{\sqrt{119} }{12}

The ratio for cos(X) is \frac{5}{12}

Step-by-step explanation:

- The ratio of the sine of a right triangle is:

sin(\alpha)=\frac{opposite-side}{hypotenuse}

Since we need the ratio for angle X, \alpha =X. From the picture we can infer that the opposite side of X is \sqrt{119}. The hypotenuse (the side opposite to the right angle) is 12, so replacing the values:

sin(X)=\frac{\sqrt{119} }{12}

- The ratio of the cosine is:

cos(\alpha)=\frac{adjacent-side}{hypotenuse}

Similarly, \alpha =X, adjacent side = 5, and hypotenuse = 12, so

cos(X)=\frac{5}{12}
