Given right triangle MNO, which represents the value of cos(M)?
A. ON/MN
B. MN/MO
C. ON/MO
D. MN/ON

Answer:
Option B. MN/MO
Step-by-step explanation:
In a right angle triangle cosine of any acute angle = Base/ Hypotenuse
In the ∠ NMO Hypotenuse is MO and base of the triangle is MN.
Therefore cos (M) = Base / Hypotenuse = MN / MO
Therefore option B is the right answer.
Answer: OPPTION B
Step-by-step explanation:
Given a right triangle, the cosine of an angle is:
[tex]cos\alpha=adjacent/hypotenuse[/tex]
Therefore, given the triangle MNO, you can conclude that cos(M) is the one shown below:
adjacent=MN
hypotenuse=MO
Then:
[tex]cos(M)=MN/MO[/tex]
