Help!! What is the relationship between the corresponding angle bisectors BD and XZ?

Mathematics
1 answer:
Harrizon [31]3 years ago
8 0

Answer:

XZ = 2.5 BD

Step-by-step explanation:

Comparing the two triangles,

\frac{BD}{BC} = \frac{XZ}{XY}

\frac{6}{8} = \frac{XZ}{20}

⇒ XZ = \frac{20*6}{8}

         = 15

XZ = 15

So that,

BD:XZ = 6:15

           = 1:2.5

Therefore, the relationship between BD and XZ is XZ = 2.5 BD.
