A20-foot ladder is leaning against a tree. the bottom of the ladder is 12 feet away from the bottom of the tree. approximately how high up the tree does the top of the ladder reach? a2.4 feet b6 feet c9.2 feet d16 feet

You need to use pythagorean theorem
20 is the hypotenuse, so

12^2 + b^2 = 20^2
144 + b^2 = 400
b^2 = 256 
b = 16

D. 16 feet

128/3reason being 5 and 1/3 = 16/316/3 • 2/3 = 32/31 and 1/3 = 4/3 32/3 • 4/3 this will equal 128/3

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
