Answer 1

Answer:

x=20

Step-by-step explanation:

It all equals 360º and there are two of each angle. So, we can add 5x+5x+(3x+20)+(3x+20)=360º. Subtracted 40 and simplify. So 16x=320.So divide by 16 and you get that x=20.

What is a function?

A function is a statement, tenet, or rule that establishes a connection between two variables. Mathematics is replete with functions, which are necessary for the construction of intricate relationships.

The result of the calculation that the mathematical model depicts is the expression's result when the necessary parameters and natural laws are given values.

The table represents a function.

x     f(x)

-1     5

0     10

2     8

9     14

In the above table, we can see that at the value of x = 2 in the function the value of the whole function is 5.

Find the area of the figure

Answers

Answer:

  89 m²

Step-by-step explanation:

It should be no surprise that the area can be found as the difference between the area of the enclosing rectangle and the area of the triangular cutout.

The rectangle area is given by ...

  A = LW

  A = (13 m)(8 m) = 104 m²

The base width of the triangular cutout is 13 m - 4 m - 4 m = 5 m. The area of that cutout is given by ...

  A = 1/2bh

  A = 1/2(5 m)(6 m) = 15 m²

Then the area of the shaded figure is ...

  104 m² -15 m² = 89 m²
