Answer:

Step-by-step explanation:
Combine like terms (terms with the same exponent).

"Standard form" means to list terms so the exponents go from high to low (descending order).
15 degrees lower than 7 degrees means that we have to subtract.
So we have 7 degrees and it wants 15 degrees lower, so we would do 7 - 15
And so 7-15 = -8
So 15 degrees lower than 7 degrees would be -8 degrees. :)

Your question is calling the figure ABCD, but the image is showing PQRS
Using the letters that you wrote:
Because the figure was only rotated and not scaled , the sides with the same letters would still be the same
So AB would be the same as A'B' ( Length of AB = Length of A′B)
and
BC = B'C'
CD = C'D'
AD = A'D'
Or by the picture:
PQ = P'Q'
QR = Q'R'
RS = R'S'
PS = P'S'
