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

180(n-2)

Since a pentagon has 5 sides, the sum of its interior angles is

180(5-2) = 180 \cdot 3 = 540

Since it is a regular pentagon, all sides and angles are the same, so one single angle measures

\dfrac{540}{5} = 108 degrees.

If BE = 2x + 2, BD = 5× - 3, and AE = 4× - 6, what are the values of x and AC?​
hichkok12 [17]

Answer:

x = 7

AC = 44

Step-by-step explanation:

Find the diagram attached

According to the parallelogram,

BD = 2BE

5x-3 = 2(2x+2)

5x-3 = 4x+4

5x-4x = 4+3

x = 7

Hence the value of  x is 7

Also AC = 2AE

AC = 2(4x-6)

AC = 8x - 12

AC = 8(7) - 12

AC=  56-12

AC = 44

Hence the measure of AC is 44

What is the equation in slope-intercept form of a line that is perpendicular to y=13x+2 and passes through the point (3, 1)? Ent
geniusboy [140]

Answer:

y = -1/13x + 1 3/13

Step-by-step explanation:

y = 13x + 2

Perpendicular

y = -1/13x + b

Finding b:

1 = -1/13 * 3 + b

1 = -3/13 + b

1 3/13 = b

y = -1/13x + 1 3/13

Please let me know if I'm wrong :)
