Answer:
The answer is
56.01m
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
