the sum of the interior angles of a quadrilateral is 360°
[360 - (40 * 2)] : 2 =
280 : 2 =
140°
-------------------------------
140 + 140 + 40 +40 = 360°
Start with the smallest square number, it is zero but assuming they don’t want this answer so we will try with 1:
So n * 10 = 1
n= 1/10
n= 0.1
Answer:
Step-by-step explanation:
The formula for the arithmetic sequence is
, where
n is the position of the number you are looking for, a₁ is the first number in the sequenc, and d is the arithmetic difference (the difference between each number in the sequence). For us:
n = 20,
a₁ = 12, and
d = 3. ∴
our formula is this one:
and
and
so
a = 69
