Solving for x in the given images; we have; x = 157/12 and x =11 respectively.

Congruent triangles

From the law of Congruence in the first image (triangle)

We have;

  • 15/21 = (3x-4)/(5x -16)

  • 75x -241 = 63x -84

  • 12x = 157

  • x = 157/12

For the second image;

We have;

  • (2x +6)/32 = 52.5/60

  • 120x + 360 = 1680

  • 120x = 1320

  • x = 11
