Let's first find the sum of the interior angles in this polygon. We can use the equation (n - 2) x 180.
There are 8 sides on this polygon, so (8 - 2) x 180 = 1080 degrees.
Now that we know the sum of the interior angles, we can find the value of z by adding up all of the given values for the interior angles and setting the sum equal to 1080.
(134) + (2z - 15) + (2z + 1) + (2z) + (z + 44) + (2z) + (147) + (2z - 12) = 1080
299 + 11z = 1080
11z = 781
z = 71 degrees
Hope this helps! :)
Part A:
We see that this pair of equations has 1 solution. On a graph, the solutions of 2 (or more) lines is where the lines intersect. In this case, since these lines intersect 1 time, they have 1 solution.
Part B:
As previously mentioned, the solutions of multiple lines is where the lines intersect. In this case, since they intersect at (4,4), that is the solution.
The answer for this question is gonna be .5 or 1/2
Vertex = (1/2,5/2) x= 1 + or - square root of 5-2y all over 2
Answer: 5x^4
Step-by-step explanation: When simplifying combine like terms, in this case all X's will be combined together to make x^4, the 5 would be left alone.
x*5*x*x*x= 5 * x*x*x*x = 5x^4
