Yair Padilla · Answer 1

The length of the beam to the nearest tenth of a foot is 15.7 feet

Alena · Answer 2

For this case we have the following equation:

y = 9sec (theta)

From here, we must replace the following value of the angle:

theta = 55 °

Substituting we have:

y = 9 * sec (55 °)

y = 15.69102116

Rounding off we have:

y = 15.7 feet

Answer:

The length of the beam is:

y = 15.7 feet
