a 5ft pole is situated on top of a building. a 25ft pole extends from the top of the pole to a point on the ground creating a 26 degree angle. find the height of the building. please help me work this problem

  1. Reiny

    I see a right-angled triangle with an angle of 26° at the ground, an opposite side of (x+5) and a hypotenuse of 25
    so
    (x+5)/25 = sin 26
    x+5 = 25sin26
    x = 25sin26 - 5 = 5.595
