Step-by-step explanation:
Remember:

Let's plug in!

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.
Answer: 31.5
area of a triangle= bh/2 —> 7 times 3 divided by 2 equals 10.5
area of a rectangle = bh —> 7 times three equals 21
21+10.5=31.5
