Question

Enter your answer as: m,n

Answer 1

m = 2

n = 4

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
