Answer:

YZ = 8.5

Step-by-step explanation:

Since RY is an angle bisector then the ratio of the sides of the triangle are equal to the corresponding ratio of the base, that is

\frac{YX}{YZ} = \frac{XR}{ZR} , substitute values

\frac{11.9}{YZ} = \frac{7}{5} ( cross- multiply )

7YZ = 59.5 ( divide both sides by 7 )

YZ = 8.5
