Answer:
The answer to your question is:
cos α = 9/ 41
tan α = 40/9
Step-by-step explanation:
Data
cos α = ?
tan α = ?
sin α = 40/41
Process
sin Ф = opposite side / hypotenuse
then, if sin α = 40/41,
opposite side = 40
hypotenuse = 41
Pythagorean theorem
c² = a² + b²
41² = 40² + b²
b² = 41² - 40²
b² = 1681 - 1600
b² = 81
b = 9
adjacent side = 9
Now,
cosine Ф = adjacent side / hypotenuse
cos α = 9/ 41
tangent Ф = opposite side / adjacent side
tan α = 40/9

Answer:
C. 2mn and mn^2
Step-by-step explanation:
All of the other options are like terms.
Option A: -x+3x=2x
Option B: 4a+7a=11a
Option D. 3p^2q+(-p^2q)=2p^2q
Option C: These terms are not like terms since 2mn is not squared while mn^2 is squared.
Hence,
the correct option would be C.
