Answer:
My proof is in the explanation.
Step-by-step explanation:
This is a two-column proof.
One column for statements and the other for the reason for that statement.
Hopefully it shows up well on your screen. Let me know if it doesn't.
Statement | Reason
1) CD is the perpendicular 1) Given
bisector of AB
2) AD=DB 2) Definition of bisector
3) CD=CD 3) Reflexive property
4) mAngleCDA=90 4) Definition of perpendicular
5) mAngleCDB=90 5) Definition of perpendicular
6) mAngleCDA=mAngleCDB 6) Substitution property
7) Corresponding parts of each 7) SAS
triangle are congruent (side-angle-side)
8) AC=CB 8) The two triangles are ............................................................................congruent so
the corresponding parts ............................................................................are
congruent.
area of quadrilateral (rhombus)=<u>4square units</u>
<u>:</u>
Solution given:
diagonal 1:AC=2 unit
diagonal 2:BD=4 unit
it looks like a rhombus
so
area of quadrilateral (rhombus)
=½*(diagonal 1*diagonal2)=½(2*4)=4 square units
Answer:
(A) 7/(m+4)
Step-by-step explanation:
When fractions have a common denominator, you add them by adding their numerators and using that sum with the common denominator.
Here, you may be able to cancel a common factor from numerator and denominator to simplify the expression further.
