To find the answer we simply work out the equation.
cos (75) = 10/x
cos (75) * x = 10. Here, I simply multiplied both sides by x to move x to the left hand side of the equation.
x = 10 / cos (75) Here, I divided cos (75) on both sides to move cos (75) to the right hand side of the equation.
The cosine of 75 is 0.92175127, so, 10 / 0.92175127 = 10.8489137
Subtract two from your get 2
Simple...
you have:

and

Now, the first one is easy just divide it...

Now....

Multiply the whole number*denominator...
4*8=32
Now add the numerator....
32+3=35
Now use the original denominator...

Now divide...

Thus, your answer.
Answer:
Subtract property of deviation becasue your subtracting 6y frrom both sides of the equation.
Step-by-step explanation:
1)Given: 12y - 40 - 4y = 6y - 18
2)Simplify by adding 12y + (-4y): 8y - 40 = 6y - 18
3)Subtract property of deviation: 8y -6y - 40 = 6y -6y - 18
2y - 40 = -18
