Let A and B are two angles, in which  A is " \frac{1}{2} " complementary angles  and B be is another complementary angle.

Condition of complementary angle :

A+B =90 ......(i)

Solution:

\ A = \ 3B - 18 \\\\ \ put \ the \ value \ of \ A \ in \ equation.....(i) \\\\  \ Equation:  \\ \\\Rightarrow  \ A\ +\ B \ =\ 90 \\\\\Rightarrow \ 3B\ -\  18 \ + \ B \ = \ 90 \\\\\Rightarrow \ 4B \ = \ 90 +18 \\\\\Rightarrow \ 4B = 108 \\\\ \Rightarrow  B = \frac{108}{4} \\\\ \Rightarrow   B \ = \ 27\\

\ put \ the \ value \ of \ B \ in \ equation (i).\\\\ \ Equation: \\\\\Rightarrow A+B=90\\\\\Rightarrow A+27=90\\\\\Rightarrow A=90-27\\\\\Rightarrow A= 63

What is the common difference of the arithmetic sequence graphed below?
galben [10]
I think it’s -0.75. The x coordinate represents the term number so y would show the pattern which is -3.75, -4.5, -5.25, -6, -6.75, -7.5, -8.25, -9. To get to the next number, each term is being decreased by 0.75. Hope this helps :)
