A carpenter needs to measure the length of the beams that will support a roof. The building is 50 feet wide. The roof will rise at
an angle of 30° from the top of the walls. The peak of the roof is
14.43 feet above the top of the walls. The side adjacent to the 30
angle is half the width of the building.
1)How long is each support beam, b, to the nearest thousandth?
2). Add 2 feet to the beam length so that the roof can extend 2
feet past the walls. What is the total beam length?
3). What is the cosine of 30°?
Round all side lengths to the nearest thousandth and round angle
measures to the nearest degree.
