Answer:
sin 25
Step-by-step explanation:
sin(A − B) = sinA cosB − cosA sinB
sin 155
sin( 180 -25)
A = 180 B = 25
sin180 cos25 − cos180 sin25
Sin 180 = 0
cos 180 = -1
0 - (-1) sin 25
sin 25
A. <span>–13 + 27 = 27 + (–13) is an example of the commutative property.
The commutative property states that a + b = b + a.</span>
A) 3:11
