Answer:
n=−43/3
Step-by-step explanation:
−42/3=2n/3+1/3+n/3
−14=2/3n+1/3+1/3n
−14=(2/3n+1/3n)+(1/3)
−14=n+1/3
Flip the equation.
n+1/3=−14
Subtract 1/3 from both sides.
n+1/3−1/3=−14−1/3
n=−43/3

Answer:
cos W = 7/15
Step-by-step explanation:
Mathematically the cosine of an angle is the ratio of the adjacent to the hypotenuse side
From the diagram given, 14 is adjacent to vertex w and 30 faces the right angle which makes it the hypotenuse
So, we have it that;
cos W = 14/30
cos W = 7/15
