In the right triangle shown below, what is the value of x?

Round your answer to the nearest tenth.

A. 10.2

B. 9.8

C. 12.1

D. 8.5

12.1 option C

Step-by-step explanation:

By using Pythagoras Theorem,

x=12.08

x=12.1

0ption C

i need more information

step-by-step explanation:

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
