The reason for this is because they both share two pairs of angles that are the same: 40 degrees and 60 degrees. If these are equal, then that must mean the third angle for both triangles is also the same, making both triangles equal in proportion. Therefore, they must be similar.
We take each number as x = 2x 3x 4x (2x)³+(3x)³+(4x)³=33957 8x³+27x³+64x³=33957 99x³=33957 x³=33957÷99 =∛343 x=7 2x=2×7=14 3x=3×7=21 4x=4×7=28 =the three numbers are 14,21,28
