<em>Answer:</em>
<em>63°</em>
<em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>ABCD parallelogram => ∡A = ∡C</em>
<em>13x - 41 = 6x + 15</em>
<em>13x - 6x = 15 + 41</em>
<em>7x = 56</em>
<em>x = 56 : 7</em>
<em>x = 8</em>
<em>∡C = 6×8 + 15 = 48 + 15 = 63°</em>
<em>Good luck !</em>
Sum of the terms of the series is
Sn = n/2 ( a1+an )
we have n= 6 , a1= 17, an = 57
so Sn = 6/2 ( 17+57) = 3(74) = 222
Answer:
2,125,760
Step-by-step explanation:
The first term (a) is 8
The fourth term is 216
Hence the sum of the first 12 term can be calculated as follows
= 8-8(3)^12/1-3
= 8-24^12/-2
= 2,125,760
The sum of first 12 terms is 2,125,760
