If tan theta =12/5 and cos theta < 0, then sin theta is -12/13.
The correct answer between all the choices given is the last choice or
letter E. I am hoping that this answer has satisfied your query about and it
will be able to help you.
A property of rectangles is that opposite sides are congruent. In this case, since QT and RS are opposite sides, they are equal to each other. With this knowledge, you can form the equation
to solve for x.
Firstly, subtract both sides by 8: 
Next, divide both sides by 4 and your answer will be
, or the third option.
Range = -4= g(x)
Therefore, g(x) = -3x+2
or, -4=3x +2
or, 3x= -4-2
or, 3x= -6
or, x= -6/3 = -2
OPTION A is the correct answer.
