Remark
That was well worth doing. Desmos gave you the answer to the graph. Unfortunately I can only give you the correct graph. You will have to figure out from the choices which one is the correct answer -- or edit it so I can see what the rest of the question is.
Graph
The red one is f(x) is x + 3 {x <= -2}
The blue one is f(x) is x^2 - 1 {-2 <x <1} Notice the gap at 2. It is not continuous
The green one is f(x) is log_2(-x + 3) {1 <=x < 3} and there is a gap between the blue and green one.

Answer:
100°
Step-by-step explanation:
Angle AKC is a vertical angle with angle BKD, so has the same measure. Since K is the center of the circle, arc AC has the same measure as angle AKC: 100°.

Answer:
106.6
Step-by-step explanation:
There is a triangle and rectangles inside of this shape. You need to split it up so you can find all the sides of the triangle and the squares. The attached image shows me doing that.
Now you need to calculate the area for all the rectangles and triangles.
The area of a triangle is A = bh / 2
The area of a rectangle is A = lw
The area of a square is A = s^2 or s * s.
Add up the area of all geometry together to get your answer.
10.2 is the area of the triangle
17.6 is the area of 4.4 by 4 rectangle
36.5 is the area of the 8.3 by 4.4 rectangle
42.3 is the area of the 8.3 by 5.1 rectangle.
The total area of the figure shown is ≈ 106.6
