In the diagram below, circle O is circumscribed about quadrilateral DEFG. What is the value of x?
2 answers:
Answer:
A.
Step-by-step explanation:
We are told that circle O is circumscribed about quadrilateral DEFG.
Since we know that the opposite angles of quadrilateral inscribed inside a circle are supplementary.
Let us find value of x by equating the measure of x and its opposite angle with 180.
Therefore, the value of x is 61 degrees and option A is the correct choice.

f(x) = x² + 9 g(x) = 24 + 4x
f(4) = (4)² + 9 g(-1) = 24 + 4(-1)
= 16 + 9 = 24 - 4
= 25 = 20
****************************************************************
g(x) = 2ˣ - 4 f(x) = 4x² - 5x - 5
g(6) = 2⁶ - 4 f(-5) = 4(-5)² - 5(-5) - 5
= 64 - 4 = 100 + 25 - 5
= 60 = 120
***************************************************************
f(x) = (3x + 7)²
f(1) = (3(1) + 7)²
= (3 + 7)²
= (10)²
= 100

3xy + 2x² - y³ ; when x = 6 and y = -2
3(6)(-2) + 2(6)² - (-2)³
-36 + 72 - (-8)
36 + 8
44
1. Add 4 to both sides of the equation.
2. Multiply 6/5.
x=
