Answer:
60 degrees
Step-by-step explanation:
1+<2=180
<1+120=180
<1=180-120
<1=60
The vertex form:

(h,k) - the coordinates of the vertex

The coordinates of the vertex are
(-4,13).
Remark
The key step is just to subtract 5 from both sides. The pointed of the inequality still points away from the variable and towards the number. As long as that remains true, the correct answer can be found.
Solution
2.7 ≤ b + 5 Subtract 5 from both sides.
2.7 - 5 ≤ b
- 2.3 ≤ b Write with the variable on the left.
b ≥ - 2.3 <<<< answer
I believe it is 83 because a straight line is 180 degrees
radius of small circle = 16 m
radius of large circle is doubled so it will be 32 m
Area of the larger circle = π x 32^2 = 1,204π m^2
answer
1,204π m^2
