ABC is same as FDE
so AC = FE = 5ft
angle B = 28 deg
angle C = 90 deg
so A = 180 - B - C = 62
Solution :
First term, a₀ = -10 .
Common difference of A.P. , d = -8 - (-10) = 2 .
Last term, aₙ = 24 .
We know, last term is given by :
aₙ = a₀ + (n-1)d
24 = -10 + (n-1)×2
2n - 2 = 34
n = 18
Now, sum of series is given by :
Hence, this is the required solution.
Your answer should be C. X = 12
Steps to --> 10+ 6(-9 - 4x) = 10(x - 12) + 8
10 + 6 (-9 - 4x)
= 10 - 54 - 24x
= -24x - 44
10 (x - 12) + 8
= 10x - 120 + 8
= 10x - 112
-24x = 10x - 68
-24x - 10x = 10x - 68 - 10x
-34x = -68
-34x/-34 = -68/-34
x = 2
887(25) = 22175, i hope it helps
It would be: 16 / 4/9
We can re-write as: 16 * 9/4 = 4 * 9 = 36
So, your final answer is 36
Hope this helps!
