Answer:
x=8
Step-by-step explanation:
6x+42=90
6x=48
x=8
Answer:
the = sign means both sides of the equation have the same value.
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°
