step-by-step explanation:

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
