-A prime number is a whole numbergreater than 1, whose only two whole-number factors are 1 and itself. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29.

- A whole number that can be divided evenly by numbers other than 1 or itself. Example: 9 can be divided evenly by 3 (as well as 1 and 9), so 9 is acomposite number. But 7 cannot be divided evenly (except by 1 and 7), so is NOT a composite number (it is a prime number).

Answer:

Similar triangles states the length of the corresponding sides are in proportion.

In a given similar triangles:

Labelled the diagram:

Triangle BAC and triangle DAC are similar.

then;

Corresponding sides:

$\frac{AB}{AD} = \frac{BC}{DC}$

AB = x units , BC = 5 units, AD = 15 units and DC = BD-BC = 8-5 = 3 units

$\frac{x}{15} = \frac{5}{3}$

By cross multiply we get;

$3x = 15 \cdot 5$

Simplify:

$3x = 75$

Divide both sides by 3 we get;

$\frac{3x}{3}=\frac{75}{3}$

Simplify:

x = 25 units

Therefore, the value of x is 25 units.

Find the length of side x in simplest radical form with a rational denominator.60°130°X

iren [92.7K]

We will solve using the law of sines as follows:

$\frac{1}{\sin(30)}=\frac{X}{\sin (60)}$

Now, we solve for X:

$\Rightarrow X=\frac{\sin(60)}{\sin(30)}\Rightarrow X=\sqrt[]{3}$

So, the length of X is sqrt(3).
