 Karen has a ladder that is 18 feet long. She wants to lean the ladder against a vertical wall so that the top of the ladder is 17.3 feet above the ground. For safety reasons, she wants the angle the ladder  makes with the ground to be no greater than 75°. Will the ladder be safe at this height ? Show work

We can use the sine inverse to find this

 

asin ( 17.3 / 18)  =  73.96°   .....It is safe  !!!
