# A radio transmission tower is 210 feet tall. How long should a guy wire be if it is to be attached 11 feet from the top and is to make an angle of 26° with the ground?

$453.95 f t$

#### Explanation:

$210 - 11 = 199 f t$ top of guy wire

$\therefore \text{hypotenuse"/"opposite"= "cosec} {26}^{\circ}$

$\therefore \text{hypotenuse"/199="cosec} {26}^{\circ}$

$\therefore \text{hypotenuse"= "cosec} {26}^{\circ} \times 199 f t = 453.95 f t$ length of guy wire
