You want to measure the height of a tree growing vertically on the side of a hill. the hill makes an angle of 20°with the horizontal. standing 15ft. downhill from the base of the tree, you measure the angle formed by the hill and the top of the tree to be 45°. find the height of the tree to the nearest foot. show your work.

step-by-step explan mxfcg'k; uafwgzfgjhklhgation:

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
