5. The side lengths of quadrilateral CDEF are as follows: CD = 4 cm, DE = 5 cm,
EF = 8 cm, and CF = 7 cm. The figure is
rotated 180° about the vertex C. What
are the side lengths of the resulting
image, Figure C'D'E'F?

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

i hope this is what you were looking for.

see attached graph

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
