Answer:
Step-by-step explanation:
X²=12x-40
X²-12x+40=0
a=1 and b= -12 and c = 40
delta = b² - 4ac
delta = (-12)² - 4(1)(40) = 144 - 160 = - 16 = (4i)² ....i² = -1
x1= (12-4i)/2 =6-2i
x1= (12+4i)/2 =6+2i

Answer:
(6, -4)
Step-by-step explanation:
To solve a linear system of equations <u>graphically</u>, graph the given equations and locate where the two lines intersect. The point of intersection is the <u>solution</u> to a system of linear equations.
Given linear system of equations:

Rewrite the second equation to make y the subject:



To graph a linear equation, find two points on the line by substituting two values of x into the equation. Plot the points and draw a straight line through them.
<u>Equation 1</u>


<u>Equation 2</u>


From inspection of the graph (see attached), the point of intersection is (6, -4).

The given diagram represents a quadrilateral inside a circle .
And to find the measurement of angle 1, we have to use the following rule:
Sum of opposite angles of a cyclic quadrilateral is 180 degree.
Here one angle is 86 degree.

Subtracting 86

So the measurement of angle 1 is 94 degree.
