 Question 468934: A ladder 8ft long resting against a house makes a 60 degree angle with the ground.How far up the house does it reach? Give answer in terms with the radical in the numberatorAnswer by stanbon(57412)   (Show Source): You can put this solution on YOUR website!A ladder 8ft long resting against a house makes a 60 degree angle with the ground.How far up the house does it reach? Give answer in terms with the radical in the numerator. ----------- Draw the picture. You have a right triangle with hypotenuse = 8 ft and ground angle = 60 degrees. --- Find the height of the triangle. Solve sin(60) = height/8 --- height = 8*sin(60) = 8*(sqrt(3)/2) = 4*sqrt(3) = 6.9282 ft. ============================= Cheers, Stan H. ============
