Answer:

7.065 sq. units

Step-by-step explanation:

The circumference is given, thus you can use the equation 2πr = circumference to find out the radius first, r = 1.5.

Area = πr²

∴The required area is 7.065 sq. units

Jeff works in the Klein Forest cafeteria. When A-lunch begins, he has already prepared 50lunches. He will prepare 10 lunches per
olga_2 [115]

The function is L = 10m + 50

Here, we want to find out which of the functions is required to determine the number of lunches L prepared after m minutes

In the question, we already had 50 lunches prepared

We also know that he prepares 10 lunches in one minute

So after A-lunch begins, the number of lunches prepared will be 10 * m = 10m

Adding this to the 50 on ground, then we have the total L lunches

Mathematically, that would be;

L = 10m + 50

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.
