Answer:Under↓↓↓
Step-by-step explanation:
-x=3x-4 (substitute -x for y)
-4x=-4 (Subtract 3x from both sides)
x=1 (Divide both sides by -4)
Since y=x then y=1
L=4+W
46=2L+2W
46=2(4+W)+2W
46=8+2W+2W
46=8+4W
38=4W
9.5=W
L=4+9.5
L=13.5 in.
Hope this helps. I can explain more if needed!!
I am not sure what the question is but here is how you use trig functions:
sine of the angle = side opposite the angle ÷ hypotenuse
cosine of the angle = side adjacent to the angle ÷ hypotenuse
tangent of the angle = side opposite the angle ÷ side adjacent to the angle
