Find the length of GH

y=√(x1-x2)^2+(y1-y2)^2

y=√(-3-(-11))^2+(15-0)^2

y=√8^2+15^2

y=√64+225

y=√289

y=17

Step-by-step explanation:

17

Step-by-step explanation:

x₁ = -3 and x₂ = -11

y₁ = 15 and y₂ = 0

√(-3 - -11)² + (15 - 0)²

√( 8² ) + ( 15² )

17

e) none of the above because the measure of angle cba is 101°

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
