Question

What answer is this If m = 70° and m = 30°, then m 2 =

Answer 1

Ill say  angle 1, that is 1/2 the difference of two arcs i.e. (Big -small)/2

VU- ST/ 2 = angle 1

replace the formula 20 and angle 1 with 30

VU-20/2=30

So VU-40=60

(VU-20)/2 =30.2                             Anw:  (So UV = 80)
