Answer:
3x-27
Step-by-step explanation:
<BEC=<AED
Substituting x=30 in the expression 2x+30
2x+3=2(30)+3=63
The expression 3X-27 is also
3(30)-27=63

Answer:
Step-by-step explanation:
<u><em>The picture of the question in the attached figure </em></u>
we know that
According to the <u><em>Perpendicular Tangent Theorem</em></u>, tangent lines are always perpendicular to a circle's radius at the point of intersection
That means ----> Triangles ODC and OEC are right triangles
In the right triangle OEC
we have
----> radius of the circle
Applying the Pythagorean Theorem
substitute the given values
