Answer asap
in circle v, angle wxz measures 30°. line segments wv, xv, zv, and yv are radii of circle v.

we know that

the triangle wxv is an isosceles triangle

because

wv=vx=radius

so

m∠xwv=m∠wxz=°

the sum of the internal angles of triangle must be equal to degrees

m∠xwv+m∠wxz+m∠wvx=

m∠wvx=°

measure arc wux=m∠wvx=° > by central angle

therefore

the answer is

the measure of the arc wux is equal to

i think is g(1)=-1.

hope that i can
