What is the error in finding the angle measure? What is the correct angle measurement for angle 1?

Please show all the work on how you got your answers. (Note- I am not asking for an explanation if you can't give one. All I need is the work shown so I can see how you got your answers)

  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°.

1) D

2) 26°

Step-by-step explanation:

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

½(52) = 26

there are lots of ways.   pick's theorem tells us if the vertices are lattice points the area a is

a = b/2 + i - 1

where b is the number of boundary lattice points and i is the number of interior lattice points.

in the figure i count b=16, i=50 so

a = 8 + 50 - 1 = 57

let's try the shoelace formula.   the area is half the sum of the cross products of the sides.  

a(-2,6)   -2(2)-6(-5) = 26

b(-5,2)   -5(-3) - 2(-2) = 19

c(-2,-3) -2(-3) - (-3)(4) = 18

d(4,-3)   4(3) - (-3)(5) = 27

e(5,3)   5(3) - 3(1) = 12

f(1,3)     1(6) - 3(-2) = 12

a(-2,6)

each of the cross products is twice the area of the triangle with the associated side and one vertex the origin. so the area of abo=26/2=13.

area = (1/2) (26 + 19 +   18 + 27 + 12 + 12) = 57

that checks!
