The sum of the angle measures of the polygon is 540°. Write and solve an equation to find the value of x. Problems- 85 degrees 5x degrees 5x degrees 5x+5 degrees 5x-10 degrees PLEASE HELP!

Respuesta :

Answer:

The measure of x is 23 degrees

Step-by-step explanation:

Here, given the values of the angles of a polygon and the total of these angles, we want to find the value of the variable x attached to these angles;

Mathematically;

85 + 5x + 5x + 5x + 5 + 5x -10 = 540

85 + 5 -10 + 5x + 5x + 5x + 5x = 540

80 + 20x = 540

20x = 540-80

20x = 460

x = 460/20

x = 23 degrees
