A firefighter is rescuing a cat in a tree. If the branch that the cat is on is 15 feet above the
ground and the ladder makes an angle of 63°
with the ground, how long is the ladder

no not all of them.

step-by-step explanation:

some of them have a square base.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

the square root of what number? if you add that, then someone will probably answer the question.

answer: the answer is ann
