Given: circle o; angle a intercepts arc b c d ; angle d intercepts arc b c prove: angle a is-congruent-to angle d two statements are missing reasons. what reason can be used to justify both statements 2 and 3? statements reasons 1. circle o; angle a intercepts arc b c. angle d intercects arc b c 1. given 2. measure of angle a = one-half (measure of arc b c) 2. ? 3. measure of angle d = one-half (measure of arc b c) 3. ? 4. measure of angle a = measure of angle d 4. substitution property 5. angle a is-congruent-to angle d 5. definition of congruent angles inscribed angles theorem third corollary to the inscribed angles theorem central angle of a triangle has the same measure as its intercepted arc. angle formed by a tangent and a chord is half the measure of the intercepted arc.

"curse these trig-loving pirates! " devora mutters as she looks at the map. then, after thinking for a moment, she walks back to the entrance of the secret cave, measuring 48 meters along the way. after performing a calculation, devora walks back to the empty treasure, faces the entrance, and turns a certain number of degrees to her left before walking 89 meters to the treasure. supposing that the angle at the cave entrance is acute and that devora's calculations were correct, how many degrees did she turn?
