The diagram shows 2 congruent regular polygons joined together. Work out the number of sides of each polygon. The exterior angle
Svetlanka [38]

Answer: There are five sides in a polygon.

Step-by-step explanation:

Since we have given that

Measure of exterior angles = 72°

We need to find the number of sides of  polygon.

As we know the formula for "Number of sides of polygon".

Number of sides is given by

\frac{360^\circ}{72^\circ}\\\\=5

Hence, there are five sides in a polygon.

18. If (2x-3) is a factor of 2x4 - 3x² + 15x - 15k,<br> find the value of (3k - √5 k).
k0ka [10]

Answer:

Well, here it means that if we set 2x-3 to zero, it becomes x over two dimensions. If we set the question form to zero and set x to two over two

k is obtained 19 to 12, now put this k in what you want

Expand<br> (2x - 3)4 <br><br> Can you help me expand this by using the binomial theorem?
saw5 [17]

The value of expanding (2x -3)^4 is 16x^4  + 96x^3  +216x^2 -216x + 81

<h3>How to expand the expression?</h3>

The expression is given as:

(2x -3)^4

Using the binomial expansion, we have:

(2x -3)^4 = ^4C_0 * (2x)^4 * (-3)^0 +^4C_1 * (2x)^3 * (-3)^1 + ^4C_2 * (2x)^2 * (-3)^2 + ^4C_3 * (2x)^1 * (-3)^3 + ^4C_4 * (2x)^0 * (-3)^4

Evaluate the combination factors.

So, we have:

(2x -3)^4 = 1 * (2x)^4 * (-3)^0 + 4 * (2x)^3 * (-3)^1 + 6 * (2x)^2 * (-3)^2 + 4 * (2x)^1 * (-3)^3 + 1 * (2x)^0 * (-3)^4

Evaluate the exponents and the products

(2x -3)^4 = 16x^4  + 96x^3  +216x^2 -216x + 81

Hence, the value of expanding (2x -3)^4 is 16x^4  + 96x^3  +216x^2 -216x + 81

Suppose the triangles are similar:

The side lenghts would be proportional as follows

XZ/DF = XY/DE

12/8 = 9/x cross multiply expressions

12x = 72 divide both sides by 12

x = 6
