Here is the correct answer, and explanation for how to get the answer, and a way to remember how to use them for next time :)
Value of x = 19
(8x - 20) = (5x + 37)
3x = 57
x = 19
2*27= 54 which is an even number, not a perfect square, odd or prime. The prime factorization would be 2*3^3
B, Even
Answer:
12 sides
Step-by-step explanation:
Given that :
Two of the exterior angles are = 60
The rest are each 24 ;
Find n, the number of sides of the polygon
The sum of the exterior angles of a polygon = 360
2 of the angles are 60° each ;
360 - (2 * 60)
360 - 120 = 240°
The remaining sides are 24° each ;
Hence, number of sides that are 24°
240° / 24° = 10 sides
Hence, total number of sides :
10 sides (14° each) + 2 sides (60° each)
10 + 2 = 12 sides
