Answer:
36°
Step-by-step explanation:
From the question,
The sum of the exterior angle of a polygon = 360
From the diagram. the polygon is Decagon
Note: A Decagon is a polygon with 10 sides.
number of sides = 10 .
The exterior angle of a regular polygon = sum of the exterior angle/number of sides.
Exterior angle = 360/10
Exterior angle = 36°
Hence the measure the single extrior angle = 36°
Option A:
The equation for the trend line is y = 82x + 998.
Solution:
The points on the line are (2, 1162) and (11, 1900).
Here,
Slope of the line:
m = 82
Point-slope formula:
Add 1162 on both sides of the equation.
The equation for the trend line is y = 82x + 998.
Hence Option A is the correct answer.
Answer
The first one is equal and the second one is the first choice.
Answer:
5.
x + 2(x + 1) = 8 --> x = 2
y = 2 + 1 = 3
7.
3(9 + 2y) + 5y = 20 --> y = -7/11
x = 9 + 2(-7/11) = 85/11
9.
3(-1 - 2y) + 5y = -1 --> y = -2
x = -1 - 2(-2) = 3
