Since this is a polygon with 6 sides, it has a total of 720 degrees.
<span>
So adding together all the angles, you get:
(2x-50) + (x+40) + (x+20) + x + 150 + 80.
Simplify.
5x+240. And since you know all the angles add up to 720 degrees, set it equal to each other.
5x+240 = 720
5x= 480 (720-240)
x= 96
Finally, plug in x to get the rest of your answers.

U r greater then 60 and less then 85
u r a multiple of 9......multiples of 9 between 60 and 85 are :
63,72,81
u r an even number......only leaves one answer and that is : 72 <==
Answer:
y = 1/2x +4
Step-by-step explanation:
You are given the slope (m) of the line and a point, and asked for slope-intercept form:
y = mx +b . . . . . . . line with slope m and y-intercept b
The value of the intercept, b, can be found from the point by rearranging this equation to ...
b = y -mx
b = 1 -1/2(-6) = 4 . . . . using x=-6, y=1
Then the equation of the line with m=1/2 and b=4 is ...
y = 1/2x +4
When x= -3
7-2(-3)
=7+6
=13
