We have been given that secants AC and DB intersect at point E inside the circle. Given that the measure of arc 
, arc 
, and arc 
. We are asked to find the measure of angle AED.
We know that the measure of angle formed by two intersecting secants is half the sum of measure of the arcs by intercepted by the angle and its vertical angle.
Let us find measure of arc AD by subtracting measure of given arcs from 360 degrees as:
Therefore, measure of angle AED is 130 degrees and option C is the correct choice.
To solve using completing square method we proceed as follows:
x^2-10x+8=0
x^2-10x=-8
but
c=(b/2)^2
c=(10/2)^2=25
thus we can add this in our expression to get
x^2-10x+25=8+25
factorizing the LHS we get:
(x-5)(x-5)=33
(x-5)^2=33
getting the square roots of both sides we have:
x-5=+/-√33
x=5+/-√33
Answer:
It is not valid since there is more than one variable being changed at one.
