I think the answer is 5:1
<span><span>Well, since we know that sin(x) = cos(90-x), we can transform the given into
2x - 8/3 = 90 - (4x - 10/3)
2x - 8/3 = 90 - 4x + 10/3
Now clear fractions by multiplying by three...
6x - 8 = 270 - 12x + 10
6x - 8 = 280 - 12x
18x = 288
x = 16
4x - 10/3 = 4(16) - 10/3 = 64 - 3.33 = 60.67 degrees.

Answer:
6y+66
Step-by-step explanation:
write the problem out, placing 6 on its own, and the sum of y and 11 inside a pair of parentheses after the 6.
6(y+11)
then, just use the distributive property and multiply each term inside the coefficients by six. you'll get 6y+66 as your final answer.
if your teacher says that the final answer is not supposed to have variables in it, then we'll need a bit more information.
