Answer:

z = 17.5

Step-by-step explanation:

segment RX is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is

\frac{RS}{RT} = \frac{SX}{TX} , substitute values

\frac{15}{z} = \frac{6}{7} ( cross- multiply )

6z = 105 ( divide both sides by 6 )

z = 17.5

Cross products: a/b = c/d is also equal to ad = bc

so, essentially you’re just drawing two diagonal lines from one side to the other, multiplying those numbers together, and setting them equal

so: 4/6 and 14/21 = (4*21 = 6*14) = (84 = 84)

84 is equal to 84 so these two ratios are equivalent.
