Answer:

Part a) [tex]93,826.8[/tex]

Part b) [tex]BC=3.7\ units[/tex]

Step-by-step explanation:

Part a) we know that

[tex]40\%=40/100=0.40[/tex]

To find out the 40% of 234,567, multiply the number 234,567 by 0.40

so

[tex](0.40)(234,567)=93,826.8[/tex]

Part b) we know that

BA is perpendicular bisector of DC

That means

,[tex]\angle BED=\angle BEC=90^o[/tex]

[tex]ED=EC[/tex]

so

The triangles BED and BEC are congruent by SAS Congruence Theorem

BED≅ BEC

Remember that

If two figures are congruent, then its corresponding sides and its corresponding angles are congruent

therefore

BD ≅ BC

we have that

[tex]BD=3.7\ units[/tex]

so

[tex]BC=3.7\ units[/tex]
