Answer 1

Answer:

1) D

2) 26°

Step-by-step explanation:

The difference should have been divided by 2 (multiplied by ½)

½(52) = 26

Answer 2

Answer:

  see below

Step-by-step explanation:

You found that when secants/chords meet inside the circle, the angle where they meet is half the sum of the intercepted arcs.

When the secants/tangents meet outside the circle, the angle where they meet is half the difference of the intercepted arcs.

The working shown is good as far as it goes. The difference needs to be multiplied by 1/2.

The angle is (122° -70°)/2 = 52°/2 = 26°.
