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
