Answer: Option C is correct
Step-by-step explanation:
We know tha tCos(A-B) = cosA cosB + sinAsinB
Plugging A = 180 and B = Ф
cos(180-Ф)= cos180cosФ+sin180sinФ
= (-1) cosФ+ (0) sinФ [ since cos180=-1 and sin180 =0]
= -cosФ + 0
= -cosФ
Therefore option C is the correct answer.
The variable <em>x </em>is equal to 0.5
5. m=3 because 6/2 is the slope. b= 1
6. m= -4 because -20/5 is the slope. b= 140
Answer:
Just plus everything together
X-3+4X+4+2X+1
