The number 7 should be removed from his list to make the list accurate.
Cos( A + B ) = cosAcosB - sinAsinB ;
cos( A + B ) / ( cosAsinB ) = ( cosAcosB - sinAsinB ) / ( cosAsinB ) = ( cosAcosB ) / ( cosAsinB ) - ( sinAsinB ) / ( cosAsinB ) = cosB / sinB - sinA / cosA = cotB - tanA ;
Answer:
380
Step-by-step explanation:
You just have to substitute the variables for the number value.
(4x2 +3x4)x(2x3x4-5)
(8+ 12)x(24-5)
(20)x(19)
=380
Answer:
yes
Step-by-step explanation:
because when there is a negative sign before the number, it means that the number being shown is below zero, so yes -8.4 degrees celsius is below zero degrees celsius.
