Supplementary angles are angles that add up to 180 degrees. Oftentimes, we see that supplementary angles are on a straight line, of which is also equal to 180 degrees.
x + y = 180
x + 116 = 180
x = 64 degrees
Hope this helps!! :)
Well then let's try and find the pattern!
When we add 1 through 10, we can also say that we're adding all of these values together:
1 + 10 = 11
2 + 9 = 11
3 + 8 = 11
4 + 7 = 11
5 + 6 = 11
So we can also say that this is like multiplying 11 * 5 = 55
If we add up to 100, we can see that it's like multiplying 101 * 50 = 5050
From this, we can get an equation:
(x + 1) * (x/2)
So let's plug in 10000 into this equation:
(x + 1) * (x/2)
(10000 + 1) * (10000/2)
10001 * 5000 = 50005000
Answer:
C 50005000
Year 1: 500 + 0.25*500 = 500 [1 + 0.25]
Year 2: 500*[ 1 + 0.25] * [1 + 0.25] = 500 [1 + 0.25]^2
Year x: 500 [1 + 0.25]^x
Option d: A(x) = 500[1 + .25]^x, where .25 is the interest rate
Hope it helps, the question wasn't clear, so sorry if the answer is wrong
