Answer:
x = 84
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5, thus
sum = 180° × 3 = 540°
Sum the interior angles and equate to 540 for x
131 + 108 + 107 + 110 + x = 540, that is
456 + x = 540 ( subtract 456 from both sides )
x = 84
Answer:
the standard form of the given number is 4.381 x 10⁶
Step-by-step explanation:
Given number = 4381 x 10³
The above number can also be written as; 4381.0 x 10³
In standard form, the decimal point will be moved three steps backward to the first digit (4) and the resulting is multiplied by 1000, as shown in the number below;
4381.0 x 10³ = 4.381 x 10³ x 1000
= 4.381 x 10⁶
Thus, the standard form of the given number is 4.381 x 10⁶
