Answer 1

Your answer would be answer A: 8

Answer 2

length of each is 51

Explanation:

they are congruent triangles so they are equilateral

therefore, you can set 7x - 5 and 5x + 11 equal to each other and solve for 'x'

2x = 16

x = 8

Substitute 8 into each expression and both come out to be 51
