Using cross multiplication,
30 x 14 = 20 x w
so
w = 420/20
w = 21
Answer:
Step-by-step explanation:
We know that . Rounding the value of b as asked in the problem gives b=12.
From the right-triangle definition of cosine, b must be the adjacent side to the angle 22.6º and the hypothenuse of the triangle must be 3.
Then, a is the opposite side of the angle 22.6º therefore using the definition of sine, . Solving for a, we obtain .
We conclude that .
32 x4 because you are multiplying four rows to make 32
Answer:
C. 60 degrees.
Step-by-step explanation:
Sin theta = opposite / hypotenuse
= 3 sqrt3 / 6
= sqrt3 / 2.
So theta = arcsin (sqrt3/2)
= 60 degrees.
