Answer:
Step-by-step explanation:5
80
Step-by-step explanation:
1. Find an area of 1 triangle:
5x8x1/2=20
2. Multiple by 4
20x4=80
For this case what you have to take into account is the following trigonometric relationship:
TanB = b / a
We clear the value of b:
b = a * TanB
Substituting the values we have:
b = 10 * Tan (60)
b = 17.32 m
Answer:
b = 17.32 m
option a.
