Answer:
BC = 205.8 feet
Step-by-step explanation:
Please see attached photo
From the attached photo:
Angle B = 71°
Adjacent = BD = 67 feet
Hypothenus = BC = x
The value of x can be obtained as follow:
Cos B = Adjacent / Hypothenus
Cos 71 = 67 / x
0.3256 = 67 / x
Cross multiply
0.3256 × x = 67
Divide both side by 0.3256
x = 67 / 0.3256
x = 205.8 feet
Therefore BC = 205.8 feet
