Question

a transmission is 100 feet tall, how long should a guy wire be if it is attached 7 feet from the top and is to make an angel of 23 degrees with the ground

Answer 1

Height of transmission 7 feet from the top =100-7=93 feet

Let the length if the guy wire be x

To cal the length of the guy wire we use;

Sin23°=93/X

X=93/sin23°

X=238 feet
