Since the sum of the angles of a triangle = 180°
Then (2x)º + (x + 60)º + (3x)º = 180°
(6x)° + 60° = 180°
(6x)° = 180° - 60°
x = 120° ÷ 6
∴ x = 20
Arithmetic sqaure: a + (n-1) * d
<em> </em><u><em>where "a" is the first term, "d" is the common difference</em></u>
Here given:
a = 10 gallons
d = 5.5 gallons
- nth term: 10 + (n-1) * 5.5
<u>Solve for first 5 terms</u>:
10 + (1-1) * 5.5 = 10
10 + (2-1) * 5.5 = 15.5
10 + (3-1) * 5.5 = 21
10 + (4-1) * 5.5 = 26.5
10 + (5-1) * 5.5 = 32
first five terms: 10, 15.5, 21, 26.5, 32
