Question

Please help: solve for x​

Answer 1

Explanation:

since the height from M (line MB) to the baseline is splitting the baseline into 2 identical halves, the triangle must be an isoceles triangle (both legs are identical long).

and therefore,

5x - 5 = 3x + 1

2x - 5 = 1

2x = 6

x = 6/2 = 3
