What is the measure of POR?

∠ PQR = 55°

Step-by-step explanation:

∠ QPR = 74° ( vertical angles )

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180°

∠ PQR = 180° - (74 + 51)° = 180° - 125° = 55°

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

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
