Hiya guys answer this please

38

Step-by-step explanation: 90 is the right angle for a right angle triangle. Therefore you subtract 90-52.

x = 38º

Step-by-step explanation:

Step one: look at the figure...it's a 90º angle (right angle)

Step two: Since it's a 90º angle you can simply subtract 90-52 which will give you the missing part (the value of x)

so therefore, x = 38º...answer a

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 correct answer is 1.7
