In this figure, sin(a) = 23

WITCHER [35]

$a$ and $b$ are complementary, or $b=\dfrac\pi2-a$ . So

$\cos b=\cos\left(\dfrac\pi2-a\right)=\sin a$

and so $\cos b=\dfrac23$ .

What is the value of x in the equation 3x-1/9y=18, when y=27?

natulia [17]

Hi Vanessa

3x -1/9 (27) =18

3x - 27/9 =18

3x- 3 =18

Add 3 to both sides

3x-3+3=18+3

3x=21

Divide both sides by 3

3x/3= 21/3

x= 7

The value of x is 7

Now let's check if my answer is correct

To check it we gonna replace x by 7 and 27 for y

(3)(7) -1/9 (27) = 18

21 -1/9 (27)=18

21- 27/9 = 18

21- 3 = 18

18 = 18

The answer is good and I hope its help:0
