Use your calculator to find the value of and the triangle to set up the ratio on the right. Solving the equation and rounding to the nearest tenth gives you . To find y, you can either use another trigonometric function (such as cosine) or you can use the Pythagorean Theorem.

We know that y is equal to x-2. We can just substitute x-2 for y since y is equal to it.

10x- 9(x-2)=24

Distribute.

10x- 9x+18= 24

x+18= 24

Subtract 18 on both sides.

x= 6

Now, plug in x.

y= (6)-2

y= 4

We can check this to see if this works:

4= 6-2, 4=4

10(6)- 9(4)= 24

60-36= 24, 24=24

x=6 and y=4

I hope this helps!

Answer:

Step-by-step explanation:

y=kx

8=-4k

k=-2

so y=-2x

$eq.~of~line~is~y-4=\frac{4-4}{1+3} =\frac{0}{4} =0\\or~y=4\\or~y=0 x+4$

eq. of line is y-5=4(x+2)
