It is true, they are congruent by doing a proof. You have to divide the trapezoid into 2 equal triangles. Then you can prove it. They are congruent since corresponding parts of congruent triangles are congruent.
Answer:
I think the answer is 7.5, because of this equation: 2x-5=10
The answer to the question is b
They can not, there are only 2 sides and they probably flipped it different ways. They got 'lucky'.
Step-by-step explanation:
Find the Center and Radius (x-4)^2+y^2=4
(
x

This is the form of a circle. Use this form to determine the center and radius of the circle.
(
x

(
y
−
k
)

Match the values in this circle to those of the standard form. The variable
r
represents the radius of the circle,
h
represents the x-offset from the origin, and
k
represents the y-offset from origin.
r
=
2
h
=
4
k
=
0
The center of the circle is found at
(
h
,
k
)
.
Center:
