Find the value of x
we know that
In an inscribed quadrilateral the opposites angles are supplementary
so
In this problem
substitute the values and solve for x
step 2
Find the measure of angle B
substitute the value of x
Answer:
AC = 6
Step-by-step explanation:
y is the dimension of the horizontal segment (see the attached image).
The hypotenuses are the same dimension, so:
(x+4)^2=(x/2)^2+y^2
(3x-8)^2=(x/2)^2+y^2
So,
(x+4)^2 = (3x-8)^2
x+4 = 3x-8
x-3x = -8-4
-2x = -12
x = 6
And x is the dimension of the segment AC.
