Answer:

35 is the length of BE

Step-by-step explanation:

2(2x + 5) = 8x - 50

4x + 10 = 8x -50

10+50 = 8x-4x

60= 4x

15 = x

2x + 5 = length of BE equal to length of DE

2(15) +5 = BE

30 +5

35 is the length of BE

What is the measure of an interior angle of a regular three-sided polygon?

noname [10]

The formula to find the measure of an interior angle is $(n - 2) * 180/n$ , where $n$ represents the number of sides in the polygon. In this problem, $n$ would represent $3$ .

Let's plug in the value for $n$
$(3 - 2) * 180/3$
Let's simplify that.
$=60$

Now we know that the <span>measure of an interior angle of a regular three-sided polygon is 60</span>°. Your answer would be B!

Let me know if you have any questions regarding this problem!
Thanks!

The sum of the measure of the interior angles of a polygon is 1980°. What polygon is it? 10-gon 11-gon 12-gon 13-gon

tiny-mole [99]

Answer:

13-gon

Step-by-step explanation:

The sum of the interior angles of a polygon with n sides is:

S = 180° (n − 2)

If S = 1980°, then:

1980° = 180° (n − 2)

11 = n − 2

n = 13
