Answer:
x = 24°
Step-by-step explanation:
<em>Here's</em><em> your</em><em> solution</em>
<em> </em> => (4x - 2) + (3x + 14) = 180°
=> 7x + 12 = 180°
=> 7x = 180° - 12°
=> 7x = 168°
=> x = 168°/7
=> x = 24°

Step-by-step explanation:
S = 1 + 3/2 + 5/4 + 7/8 + ...
½S = 1/2 + 3/4 + 5/8 + 7/16 + ...
Subtracting:
S − ½S = 1 + 3/2 − 1/2 + 5/4 − 3/4 + 7/8 − 5/8 + ...
Simplifying:
S − ½S = 1 + 1 + 1/2 + 1/4 + ...
Writing in summation form:
S − ½S = 1 + ∑ ½ⁿ⁻¹
½S = 1 + ∑ ½ⁿ⁻¹
S = 2 + 2 ∑ ½ⁿ⁻¹
Using formula for sum of a geometric series:
S = 2 + 2 (1 / (1 − ½))
S = 2 + 2 (2)
S = 6
The order is 7/15,2/3,4/5, anotherwords, its 0.46666,0.66666,0.8.
