What is the measure of each unknown angle in the polygon if each missing measurement is the same?

eighty-five degrees

seventy degrees

seventy-five degrees

eighty degrees

Answer 1

First, Mig, some background information:
The sum of the interior angles of a polygon is (n-1)*90 degrees, where n is the number of interior angles.
Check this out: determine whether this formula works for a triangle (for which n=3). what is the value of (n-1)*90 degrees?
Next: determi9ne whether the formula works for a rectangle. Here, n = ?
Next, count the number of interior angles of the polygon shown. Predict what the sum of the interior angles will be.
Can you now finish solving this problem?

Answer 2

kinda

Answer 3

How do you find what the total sum of all of the angles for certain polygons

Answer 4

is there a formula

Answer 5

Mig, I gave you that formula in my first post:

The sum of the interior angles of a polygon is (n-1)*90 degrees, where n is the number of interior angles.

Answer 6

2*90=180
