Answer:
x is 72 degrees
Step-by-step explanation:
To find the measure of x, you need to know the sum of the interior angles of the pentagon.
Sum = (n - 2) x 180
Sum = (5 - 2) x 180
Sum = 3 x 180
Sum = 540
Now divide this by 5, the number of sides
540/5 = 108 degrees for each angle of the pentagon.
To find the measure of x, look at the opposite angle, which is 108 degrees
180 - 108 = 72
The measure of angle x is 72 degrees.

Answer: 7
Step-by-step explanation:
Answer:
y = 2x² - 5x + 7
Step-by-step explanation:
General form of a quadratic is:
y = Ax² + Bx + C
Using the given points, construct equations and solve for A,B and C.
When x = 0, y = 7
7 = A(0)² + B(0) + C
C = 7
y = Ax² + Bx + 7
When x = -1, y = 14
14 = A(-1)² + B(-1) + 7
A - B = 7
A = 7 + B
When x = 1, y = 4
4 = A(1)² + B(1) + 7
A + B = -3
(7 + B) + B = -3
2B = -10
B = -5
A = 7 + (-5)
A = 2
y = 2x² - 5x + 7
