Step-by-step explanation:
7(9)-2
63-2
61
Answer:
Yes, because they have the same scale factor and look the same when graphed. It's just rotated and bigger.
Right? So if you had a ten block that would represent that for a 10 so 15 minus 10 know 5 left so we would use 5 1 blocks
Cos( A + B ) = cosAcosB - sinAsinB ;
cos( A + B ) / ( cosAsinB ) = ( cosAcosB - sinAsinB ) / ( cosAsinB ) = ( cosAcosB ) / ( cosAsinB ) - ( sinAsinB ) / ( cosAsinB ) = cosB / sinB - sinA / cosA = cotB - tanA ;
