Step-by-step explanation:

let the picture be named as above picture:

angle D +163=180 (linear pair)

D=180-163

D=17⁰

Sum of exterior angle of polygon is 360⁰.

148+50+17+90+angleC=360

198+107+angleC=360

305+angleC=360

angleC=360-305

angleC=55⁰

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
