It would be 76 degrees because it’s a vertical angle
Answer:
1, 3, 5
Step-by-step explanation:
The sum of an arithmetic series is:
S_n = n (a_1 + a_n) / 2
100 = n (1 + 19) / 2
n = 10
The nth term of an arithmetic sequence is:
a_n = a_1 + d (n − 1)
19 = 1 + d (10 − 1)
d = 2
The common difference is 2. So the first three terms are 1, 3, and 5.
(2x + 29) + 91 = 180.
This is because they add to form a straight line which is 180 degrees, in other words the angles are supplementary.
2x + 29 = 89 (Subtract 91 from each side)
2x = 60 (Subtract 29 from each side)
x = 30 (Divide 2 from each side)
x = 30
The answer is B
