Answer:
x = 125°
Step-by-step explanation:
The sum of angles in an n-sided polygon is (180°)(n -2). For a hexagon, the sum of angles is ...
(180°)(6 -2) = 720°
We can use this to find x.
x +117° +124° +102° +145° +107° = 720°
x = 720° -595°
x = 125°
This is a linear function y=mx + b
If x = 0 then y=b, if A is the point where y intercepts y-axis, the coordinates of
A(0,b)
If you want to shift the graph up by 2 units, then you have to add 2 units to b
In our case original b=7, =so to shift it up, b becomes 7+2=9
and the new function will be y=2x + 9
The sum of the first four composite numbers is 27. ( 4+6+8=9)
Answer:
Step-by-step explanation:
45 = (b(4b - 2))/2
90 = 4b2 - 2b
4b2 - 2b - 90 = 0
(2b + 9)(2b - 10) = 0
2b + 9 = 0
2b = -9
b = -9/2
If we were looking for zeroes, this would be an answer, but since we're looking for measurement, we don't use negative numbers.
90 = 4b2 - 2b
4b2 - 2b - 90 = 0
(2b + 9)(2b - 10) = 0
2b + 9 = 0
2b = -9
b = -9/2
