As We know a <u>heptagon</u> has <u>7 sides</u><u>.</u> So , we take the hexagon's sum of interior angles and add 180 to it getting us, 720+180=900 degrees.
<h3 /><h3>So Here,</h3>⇢ 129° + 116 °+ 120° +130° + 135 °+ 125° + y = 900°
⇢755° +y = 900°
⇢y = 900 °- 755°
⇢y = 145°
<h2>Hence, The Answer is <u>145°</u></h2><u></u>

Step-by-step explanation:
From the question we are told that
Matrix is given as
Generally let the change in matrix be given as X
Matlab output
Generally the matrix that makes row 2 of matrix A equal to first row of A multiplied by the negative of the first element of row 2 plus the original row is
Answer:
y = - x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 4, 0) and (x₂, y₂ ) = (0, - 7)
m = =
= -
The line crosses the y- axis at (0, - 7 ) ⇒ c = - 7
y = - x - 7 ← equation of line
