Answer:
103°
Step-by-step explanation:
The total angle in a nonagon is 1260. To get the missing angle, we add up all the given angle together and subtract it from 1260.
138 + 154º + 145° + 132° + 148° + 143 + 147 + 150 = 1157
1260 - 1157 = 103
Therefore, the missing angle is 103°

Answer:

Step-by-step explanation:
Given
Point: (-7,2)
x + 3y = -5
Required
Find B- - A in Ax + By = 3
To start with; we need to calculate the slope of x + 3y = -5

Subtract x from both sides


Divide both sides by 3


The slope of the line is the coefficient of x
Slope = 
The question says line Ax + By = 3 is parallel to line x + 3y = -5; This means that they have the same slope of 
Having calculated the slope, next is to calculate the equation of the line using the following formula;

Where m is the slope; m =
; 
Substitute these values in the formula above; the formula becomes


Cross Multiply

Open brackets

Add x to both sides


Add 6 to both sides


Multipby both sides by -3




Comparing the above to Ax + By = 3





A correct, all number of sides are calculated correctly
