Answer:

m = 2

n = 4

Step-by-step explanation:

if the two triangles are congruent then:

5m + 1 = 11  and  8m - 2n = 2m + n

Solving 5m + 1 = 11 to find m:

Subtract 1 from both sides:  5m = 10

Divide both sides by 5:           m = 2

Now substitute found value for m into 8m - 2n = 2m + n  and solve for n:

8(2) - 2n = 2(2) + n

  16 - 2n = 4 + n

         12 = 3n

          4 = n
