X/4 is the same as 1/4x, so you have the equation 1/4x + 7 = 5. subtract 7 to both sides to get the equation 1/4x = -2. then you multiply by four (which is the same as dividing by 1/4) to get x = -8
Answer:
maybe 3...............................
Your goal is to have x by itself
Send st to other side
rx= r+st
Divide by r so x stays alone
X=(r+st)/r
Which is also equal to
X=r/r+st/r
X= 1+st/r
-5 is the adjacent side, -12 is the opposite side, the hypotenuse is 13
Cos = adjacent/hypotenuse
Cos = -5/13
The answer is C.
