Answer:
Step-by-step explanation:
All radii of a circle are congruent, so by the base angles theorem
- z = y = (180-50)/2 = 65.
Also, angles x and y are inscribed in the same arc, and they are thus congruent, meaning x = 65.

Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
( substitute in values )
=
( cross- multiply )
12(x - 1) = 72 ( divide both sides by 12 )
x - 1 = 6 ( add 1 to both sides )
x = 7

The parallel line segment SV is half of RW
that is x = 7.5
SV also divides the sides RT and WT in proportion, that is
=
( cross- multiply )
10y = 24 ( divide both sides by 10 )
y = 2.4
