Answer:

75°

Step-by-step explanation:

In triangle FBG, one angle is 36. That means the other two must total 180-36=144. Assigning each one 72, their supplementary angle on the interior of the pentagon would be 108.

In triangle JDI, one angle is 39. That means the other two must total 180-39=141. Assigning each one 70.5, their supplementary angle on the interior of the pentagon would be 109.5

We now have 4 of the interior angles. Pentagons have an interior total of 540. 540-108-108-109.5-109.5=105

x is the supplement of 105. 180-105=75

y = - 4x + - 8 is equation of slope-intercept form.

What is in slope-intercept form?

Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form.
Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.

the equation of slope - intercept form

y = mx + c

( -1 , -4 ) is point shown in graph

slope = -y/x

= - ( -4)/-1 = 4/-1 = -4

- 4 = -4 * - 1 + c

- 4 = 4 + c

c = - 4 - 4 = - 8

put value of c in the equation of slope - intercept form

y = - 4x + - 8
