Answer:
B. x = 53 degrees.
Step-by-step explanation:
The external angles of all polygons add up to 360 degrees, so:
x + 120 + 90+ 97 = 360
x = 360 - 90 - 120 - 97
x = 53 degrees.
I think its C but I'm not 100% sure
85/95 is equal to 0.8947
64/76 is equal to 0.842
Therefore, 85/95 is greater
(3a-4b)²
= 9a² - 12ab + 16b²
Factors of 18: 1; 2; 3; 6; 9; 18
Factors of 27: 1; 3; 9; 27
GCF(18; 27) = 9
<span>18 + 27 = 9 × 2 + 9 × 3 = 9 × (2 + 3) </span>
