Answer:
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The triangle ABD is an isosceles triangle
because
AB=BD
The segment BM is a perpendicular bisector segment AD
so
<em>In the right triangle ABM</em>
Applying the Pythagorean Theorem
we have
substitute
-----> equation A
<em>In the right triangle BMC</em>
Applying the Pythagorean Theorem
we have
substitute
----> equation B
equate equation A and equation B
solve for x
Simplify
<em>Find the length of DC</em>
substitute the given values
