Applying the **exterior angle theorem**, the measure of angle LJK is: 28°.

Where an external angle is formed by an extended side of a **triangle**, its measure is equal to the two remote angles of the **triangle**, according to the **exterior angle theorem**.

Given the following:

m∠KLM = (7x + 3)°m∠LJK = (2x + 12)°m∠JKL = (3x + 7)°Angles LJK and JKL are remote angles of the **triangle** which are opposite the exterior angle KLM.

Therefore:

m∠LJK + m∠JKL = m∠KLM

Substitute

2x + 12 + 3x + 7 = 7x + 3

Combine like terms and find the value of x:

5x + 19 = 7x + 3

5x - 7x = -19 + 3

-2x = -16

-2x/-2 = -16/-2

x = 8

Find

m∠LJK = 2x + 12

Plug in the value of x:

m∠LJK = 2(8) + 12

m∠LJK = 28°

If the paint costs $1.50 per square meter, how much will she spend to cover the entire wall with paint?

To find the price to paint the entire wall, we just need to find the area of the wall and multiply by the price per square meter.

The area of a square is given by the product of the side length by itself. Since the measure of the side is 3 meters, the area is

[tex]A=3^2=9[/tex]**9 m²**.

The unitary price per square meter is **$1.50**. Multiplying this value by the area, we have

It will cost **$13.50** to paint the wall.

The three **numbers** are ** 61, 427 and 161.**

A** summation,** also known as a sum, is the outcome of adding two or more **numbers or quantities**. There are always an even number of terms in a summation. There could be only two terms, or there could be one hundred, thousand, or a million. There are summations with an **infinite number** of terms.

As given, one number is 7 times the first number, third number is 100 more than the first number and the sum of three numbers is 649.

Suppose the first number is x, then the second number is 7x and the third number is x + 100.

Sum of these three numbers is, 649.

x + 7x + x + 100 = 649

9x = 549

x = 61

Therefore, the first number is 61, the second number is 7x = 427, and the third number is x + 100 = 161.

Geri encarga arreglos florales para un almuerzo de agradecimiento para un maestro.Planea comprar hasta ocho arreglos de mesa que cuestan $5 cada una,con una tarifa de $10 por todo el pedido.Representa gráficamente la función para el precio.

From the graph drawn above, we can see the relationship between the flower arrangements and the cost of ordering each of them.

On the x axis you have the number of orders,and on the y axis you have the cost of each order. Each flower arrangement costs $5, and the cost of fare is $10. That means the cost for each order would shown as follows;

1 order = 5 + 10 (15)

2 orders = 10 + 10 (20)

3 orders = 15 + 10 (25)

4 orders = 20 + 10 (30)

5 orders = 25 + 10 (35)

6 orders = 30 + 10 (40)

7 orders = 35 + 10 (45)

8 orders = 40 + 10 (50)

Therefore, the ordered pair for this graph is as follows;

(1, 15), (2, 20), (3, 25), (4, 30), (5, 35), (6, 40), (7, 45), (8, 50)

That is, when x = 1, y = 15, when x = 2, y = 20..., and so on.

Antoine purchased 1.8 kilograms of apples and 315 dekagrams of oranges. This was 1,350 grams more than the weight of bananas he purchased. What was the weight of the bananas Antoine purchased in grams?

First, let's get all the values to grams.

1.8 kilograms is equal to 1800 grams.

315 deka grams is equal to 3150 grams.

1350 is already in grams.

So Antoine purchased 1800 grams of apples and 3150 grams of oranges. Adding them up, we have a total of:
