Answer:
PR = 24.5
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{KL}{PR}[/tex] = [tex]\frac{KM}{PT}[/tex], that is
[tex]\frac{28}{PR}[/tex] = [tex]\frac{18}{15.75}[/tex] ( cross- multiply )
18PR = 28 × 15.75 = 441 ( divide both sides by 18 )
PR = 24. 5
