A ladder is resting against an outside wall of a building. The ladder is extended 23 feet, and reaches a distance of 17 feet up the wall.
Using the inverse of sine, what is the angle of elevation formed where the base of the ladder rests on the ground? Round your answer to the nearest whole degree. the answer is not 43 or 44
To find the angle of elevation, we can use the inverse sine function. The length of the side opposite the angle of elevation is 17 feet, and the length of the hypotenuse is 23 feet.
sin(angle) = opposite/hypotenuse
sin(angle) = 17/23
Now, let's use the inverse sine function to find the angle:
angle = sin^(-1)(17/23)
Using a calculator, we find that the angle is approximately 41 degrees. Rounded to the nearest whole degree, the answer is 41 degrees.
