BRAINLIESTTT ASAP! PLEASE HELP ME :)

See below.

Step-by-step explanation:

Use the compound angle identity:

sin(A - B) = sinA cosB - cos A sin B.

Plugging in the given angles:

A = 360 and B = O so:

sin (360 - O) = sin 360 cos O - cos 360 sin O

sin 360 = 0 and cos 360 = 1  therefore we have  

0 * cos O - 1 * sin O

= 0 - sin O

= -sin O.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
