Question

John is standing in front of a tree at point S. He can see an arc of the tree trunk that stretches from J to K measuring 64°. What is the measure of angle JSK?

Answer 1

angle at S = (major arc - minor arc)/2

minor arc = 64
major arc = 360-64 = 296

=> angle = (296 - 64)/2 = 116 degrees

Answer 2

thank you i get it now!
