30/5 = 6 so x - 2 = 6 so x = 8
Sum_of_interior_angles = (number_of_sides - 2) × 180° → for a 30-gon sum = (30 - 2) × 180° = 5040°
Two angles are complementary if their sum equals exactly 90 degrees. Two angles are supplementary if their sum equals exactly 180 degrees, so a 30 degree angle is supplementary with a 150 degree angle.
We know that the sum of a polygon's exterior angles, one at each vertex, equals 360 degrees. So at each angle extended from each side there is an angle of 30 degrees. If x= number of sides, then 30x = 360. Divide by 30 and x = 12.
The sum of the first 30 positive integers is: 465.
The sum of the first 30 positive even numbers is 930.
The sum of divisors of a number, excluding the number itself, is called its aliquot sum
10n = -30 n = -3
To find what number multiplied by 30 equals 150, you can divide 150 by 30. This calculation gives you 5. Therefore, 30 times 5 equals 150.
It is: 30*30 = 900
30 x 30
30 x 30 = 900
30 is the Answer
what is the answer to question number 2
30 x 3
The sum of 18 + 30 is 48.
The answer all depends on the variable, or the number. It is 6 times the original number. An example: 5x5+5=25+5=30 5x6=30 x + 5x = 6x
The sum of the interior angles of a polygon can be calculated using the formula ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For a 30-gon, ( n = 30 ). Thus, the sum of the interior angles is ( (30 - 2) \times 180^\circ = 28 \times 180^\circ = 5040^\circ ).
