What is the scale factor and the Length of side X for this.

Answer:
see explanation
Step-by-step explanation:
The scale factor from smaller triangle to larger triangle, is the ratio of corresponding sides, larger to smaller
scale factor = [tex]\frac{14}{7}[/tex] = 2
since the sides of the larger triangle are twice the smaller triangle, then
x = 23 ÷ 2 = 11.5
