This is an arithmetic series, where S5 means the sum of the first 5 numbers in the series. The general formula is:
Sn = (n/2)(a1 + an)
So,
a1 = 1 + 5/2(1) = 3.5
a5 = 1 + 5/2(5) = 1.5
S5 = (5/2)(3.5+1.5)
S5 = 12.5
<em>The answer should be 12.5</em>
Answer:
1.) x = 50 2.) x = 70
Step-by-step explanation:
These angles are complementary angles meaning the angles add up to 90°. Therefore, we can set up equations to solve for the variables.
1.)
x + 40 = 90
x = 50
2.)
x + 20 = 90
x = 70
