Polygon FGHIJ is the result of the rotation of ABCDE.
A = F ⇒ 117°
B = G ⇒ 90°
C = H ⇒ 127°
D = I ⇒ 90°
E = J ⇒ 117°
The measure of angle BCD remains the same because the rotation involves the whole polygon. Thus, it is still 127°
Answer:

Step-by-step explanation:

Make denominators same:

Add the numerators:


Apply the rule:

Therefore,

Cancel out common factor of 2x+1:

The answer is -0.1 I believe
