cos(64) = ¹/₈y
8cos(64) = 8(¹/₈y)
8cos(64) = y
  8(0.44) ≈ y
      3.52 ≈ y

Answer:

The value of y is 3.51

Step-by-step explanation:

The given equation is Cos 64 = y/8

We have to calculate the value of y

Since Cos 64° = 0.43837

By putting value of Cos 64 in the equation

0.43837 = \(\frac{y}{8}\)

y = 0.43837 × 8

  = 3.5069 ≈ 3.51

Therefore, the value of y = 3.51
