Let's see what to do buddy...

_________________________________

Step (1)

We know that the sum of the interior angles of any n-sided figure is obtained from the following equation :

(n - 2) \times 180

Our figure has 5 sides ;

So , sume the interior angles of it equals :

(5 - 2) \times 180 = 3 \times 180 = 540 \\

_________________________________

Step (2)

First look at the photo which I post.

According it we have :

(180 - x) + 120 + 85 + (2x - 10) + 90 = 540 \\

2x - x + 475 - 10 = 540

x + 465 = 540

Subtract the sides of the equation minus 465 :

x = 540 - 465

x = 75

_________________________________

And we're done.

Thanks for watching buddy good luck.

I am the number of red tiles in a design with red and blue tiles. The red tiles each have 3 sides. The blue tiles each have 5 si
nekit [7.7K]
If each blue tile has 5 sides and you know you have 3 blue tiles you can multiply 5 by 3
5 x 3 = 15 sides


Next you know the total number of sides is 30 and you just figured out that your 3 blue tiles have a total of 15 sides so you can subtract 15 from 30 to find how many sides are left
30 - 15 = 15sides

Since you know that these are not blue tiles because in the question it stated that you have 3 blue tiles. These have to be sides for red tiles.

Each red tile have 3 sides so you can divide 15 by 3
15/3 = 5

There are 5 red tiles
You are the number 5

Alicia earned d dollars baby-sitting. Her friend earned twice as much. You earned $2 less than Alicia's friend earned. Write an
Semenov [28]

Answer:

Total = \$5d - 2

Step-by-step explanation:

Represent Alice with A, her friend with F and you with Y.

From the question, we have:

A = \$d

F = 2 * A --- Twice as much Alice means 2 times Alice's earnings

Y = F - 2 --- 2 less than her friend

Required

Determine the total amount

A = \$d

Substitute \$d for A in F = 2 * A

F = 2 * \$d

F = \$2d

Substitute \$2d for F in Y = F - 2

Y = \$2d - 2

The total amount is calculated by adding the earnings of Alice, her friend and you

Total = A + F + Y

Total = \$d + \$2d + \$2d - 2

Total = \$5d - 2

<em>Hence, the total earnings is 5d - 2</em>
