I believe it would be 12 because 9 min divided by .75 a rotation gets 12 rotations
Answer:i think its the first one
Step-by-step explanation:
Nothing else makes sense
The answer is $5.15! Hope this helps
Using the law os cosines formula b^2 = a^2 + c^2 - 2*a*c*cos(B)
a = 17, b = 8, c = 16
8^2 = 17^2 + 16^2 - 2*17*16* cos(B)
64 = 289 + 256 - 544 * cos(B)
544*cos(B) = 289 + 256 - 64
544 * cos(B) = 481
cos (B) = 481/544
B = arccos(481/544)
B = 27.8 degrees
X(a+b)-y(a+b)
*factor out (a+b)*
=(a+b)(x-y)
