First, we need to find the area of both the tile and cardboard, so we can calculate how much tile will fit in the cardboard

Over the next week you want to watch a movie a day. In how many ways can this be done if you have 8 movies

Leto [7]

<span>You can select from any of the 8 on the first day, leaving 7 to choose from on the second day, leaving 6 for the third. So, 8 x 7 x 6 x 5 x 4 x 3 x 2 or 8! That's 8factorial, so multiply those out or use a calculator to get 8! and that is your answer.</span>

The value of x will be equal to x = 79.

<h3>What is the triangle?</h3>

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

For an isosceles triangle, the value of two opposite angles is equal and the opposite sides are also equal.

The Sum of the three angles is equal to 180 degrees so the third angle will be calculated as:-

Angle = 180 - 142 - 19 = 19

Now applying Lami's theorem in the triangle we will get the third side.

$\dfrac{sin\angle A}{a} = \dfrac{sin\angle B}{b} = \dfrac{sin\angle C}{c}$

$\dfrac{Sin 19}{42}= \dfrac{Sin142}{x}$

$x = \dfrac{42\times Sin 142}{Sin19}$

x = 79

Therefore the value of x will be equal to x = 79.
