We know that in the right triangle cos 35=adjacent side angle 35/hypotenuse adjacent side angle 35-------------> h------>the height, of the sail hypotenuse------> 8 m so cos 35=h/8------> h=8*cos 35 remember that sec x=1/cos x so cos 35=1/sec 35 substitute h=8*(1/sec 35)------> h=8/sec 35 the answer is the option d.) 8 divided by sec 35 degrees
