Here's the solution to problem 10. Problem 10: From a point A which is 60 metres from the base of a building B and on the same level, the angle of elevation to the top of the building C is 51^, and to the top of the flagpole D on top of the building the angle of elevation is 56^. Find the height of the flagpole. Step 1: Define variables and set up the trigonometric relationships. Let AB be the distance from point A to the base of the building, so AB = 60 m. Let BC be the height of the building. Let CD be the height of the flagpole. Let BD be the total height from the ground to the top of the flagpole, so BD = BC + CD. From the given angles of elevation: For the building: (51^) = (BC)/(AB) For the building with flagpole: (56^) = (BD)/(AB) Step 2: Calculate the height of the building (BC). BC = AB × (51^) BC = 60 m × (51^) BC = 60 m × 1.23490 BC ≈ 74.094 m Step 3: Calculate the total height to the top of the flagpole (BD). BD = AB × (56^) BD = 60 m × (56^) BD = 60 m × 1.48256 BD ≈ 88.954 m Step 4: Calculate the height of the flagpole (CD). The height of the flagpole is the total height minus the height of the building. CD = BD - BC CD = 88.954 m - 74.094 m CD = 14.86 m That's 2 down. 3 left today — send the next one.
