Answer:

75 degrees

Step-by-step explanation:

Complementary angles equal 90 degrees together. That is the case with angle X and Y. Set an equation to describe the situation.

Y=1/5X

X=5Y

Now, set another equation:

X+Y=90

Substitute the first equation into the second one.

5Y+Y=90

6Y=90

Y=15

Substitute this once again:

X+15=90

X=75

What is the answer to 8x-5674=[c+-4577]<br> What is c
Artist 52 [7]
It's not completely clear what you want.   Your  <span>8x-5674=[c+-4577]  has two variables:  x and c.  You can solve this for x or you could solve it for c, but not for both.  Also, your "+-" should be written as "-"  (unless you meant "plus OR minus 4577)."

So there are several different approaches, depending upon what you meant!
If you mean this:    </span><span>8x - 5674=[c - 4577] and want to solve for c,  do the following:
1.  Remove the unnecessary brackets  [  ]
2.  Add 4577 to both sides the resulting equation.  The result will be the expression for c that you wanted.  Note that you must combine -5674 and 4577.</span>

X/(x+5) = (x-2)/(x+1)
x(x+1) = (x -2) (x + 5)
x^2 + x = x^2 - 2x + 5x - 10
 x = 3x - 10
3x - x = 10
2x = 10
  x = 5

answer is A
