In right triangle GHI, ∠H is a right angle, m∠I=42∘, and GH=11. sin42∘≈0.67 cos42∘≈0.74 tan42∘≈0.90 Triangle G H I has segment G H that measures 11 units. Angle H is a right angle and angle I is 42 degrees. What is the measurement of HI? If necessary, round your answer to two decimal places, like this: 42.53

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

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
