Anthony has told Marvin that he will come over and help him paint the sides of his house. Anthony only has a 10 foot ladder and a really good eye for angles. In order to be safe, the ladder must be
within 1 degree of 76 degrees. If Anthony places the ladder 2.5 feet from the base of the building,
will his ladder be close enough to the 76 degree angle to be safe? Explain.
Yes because Anthony's ladder will make a 75.964 degree angle.
F
G
Yes because Anthony's ladder will make a 75.522 degree angle.
H
No because Anthony's ladder will make a 14.478 degree angle.
J
No because Anthony's ladder will make a 14.036 degree angle.
