Select the correct answer.<br> What is the approximate measure of exterior angle B in the polygon?

puteri [66]

Answer:

Step-by-step explanation:

the sum of the exterior angles of a polygon = 360°

sum the 4 exterior angles and equate to 360

8x + 9x + 5 + 5x + 4 + 9x + 3 = 360 , that is

31x + 12 = 360 ( subtract 12 from both sides )

31x = 148 ( divide both sides by 31 )

x ≈ 11.23 ( to 2 dec. places )

then exterior angle at B is

9x + 3 = 9(11.23) + 3 ≈ 104° → C

Simon has a scale model of the Concorde airplane. The actual length of the Concorde is approximately 200 feet. If the ratio of t

Verizon [17]

The answer is: "40 cm " .
_________________________________________________________
<u>Note</u>:
_________________________________________________________

$\frac{200 ft }{ (x) cm} = \frac{5}{1}$ ;

Solve for "x" (in "cm" ) ;

→ 5x = 200 * 1 ;

→ 5x = 200 ;

Divide each side of the equation by "5" ;
to isolate "x" on one side of the equation; & to solve for "x" ;

→ 5x / 5 = 200 / 5 ;

to get:

→ x = 40 .

The answer is: " 40 cm " .

According to the graph, what is the value of the constant in the equation below?

Virty [35]

According to the graph, the value of the constant in the equation below is 80 and is denoted as option D.

What is a Graph?

This is defined as a pictorial representation of data or variables in an organized manner.

From the equation: Height = constant/width

We can pick any point(4,20) on the graph.

20 = c/ 4

c = 20 × 4 = 80

Orlando is measuring the angles of a triangle. He measures the first two angles and gets 30° and 70°. What should be the measure

Andrei [34K]

The answer will be B because all three angles of the triangles add up to180 degrees, and we already know the total of two other angles are 100 degrees, which made the unknown angles have 80 degrees. Hope it help!
