Answer 1

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
