Question

A 19 ft. ladder is leaning against a building that it is 13 ft. away from. Using the drawing below (not drawn to scale), find θ between the top of the ladder and the building. Round your answer to the nearest degree.

Answer 1

Answer:

43 °

Step-by-step explanation:

The ladder is the hypotenuse   13 feet is one leg of a a right triangle

   sin = opposite leg / hypotenuse

    sin (theta ) = 13 / 19

      theta = arcsin (13/19) = 43°
