The exterior angles of any convex polygon add to 360 degrees.  So for a regular pentagon, the exterior angle is 360/5 = 72 degrees. The interior angle is supplementary to the exterior angle so is 180 - 72 = 108 degrees.  So the sum of them is 5(108) = 540 degrees.

Answer: 540 degrees

The formula for the sum of the interior angles of a regular polygon in degrees is 180(n -2), where n is the number of sides on the polygon.


In the case of a regular pentagon with five sides, we can say that n = 5. Using the formula below, we can find the sum of the interior angles of the pentagon:

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


The sum of the interior angles is 540°.

36x^3a+45xa^2=9xa( ) complete the statement.
Dafna1 [17]
9xa is the common factor.

You can complete the statement by dividing the two terms of the expression of the left side by 9xa, and you will get:

36x^3a + 45xa^2 = 9xa ( 4x^2 + 5a)

Can someone please help me
Rzqust [24]

Answer:

the graph of the function is non-linear

the table can be represented by the equation y=4x+4

Step-by-step explanation:

non linear because 1+7=8 and then 10+2 = 12 so they have different numbers to add each time

represented by the equation because the x numbers (1,2,3,4,) all multiplied by 4 and added by 4 gives you y

any more help just ask :)

Is ∆JKL ≅ ∆KJM ? Justify your answer below.
makkiz [27]

Answer:

Yes, the triangles are congruent by ASA

Step-by-step explanation:

we know that

If any two angles and the included side are the same in both triangles, then the triangles are congruent by Angle-Side-Angle (ASA)

In this problem

LK=MJ

∠KLJ=∠KMJ

∠LKJ=∠MJK

so

Two angles and the included side is equal in triangle JKL and triangle KJM

therefore

JKL≅KJM ----> by ASA
