Answer:

The answer is

56.01m

Step-by-step explanation:

To find side b we use sine

sin ∅ = opposite / hypotenuse

From the question

side c is the hypotenuse and

side b is the opposite

side c = 60m

B is 69°

So we have

sin 69 = b/c

sin 69 = b / 60

b = 60 sin 69

b = 56.0148

b = 56. 01m to 2 decimal places

Hope this helps you
