Line RS intersects triangle BCD at two points and is parallel to segment DC. Triangle B C D is cut by line R S. Line R S goes th
Svetlanka [38]

Answer:

The correct options are;

1) ΔBCD is similar to ΔBSR

2) BR/RD = BS/SC

3) (BR)(SC) = (RD)(BS)

Step-by-step explanation:

1) Given that RS is parallel to DC, we have;

∠BDC = ∠BRS (Angles on the same side of transversal)

Similarly;

∠BCD = ∠BSR (Angles on the same side of transversal)

∠CBD = ∠CBD = (Reflexive property)

Therefore;

ΔBCD ~ ΔBSR Angle, Angle Angle (AAA) rule of congruency

2) Whereby  ΔBCD ~ ΔBSR, we therefore have;

BC/BS = BD/BR → (BS + SC)/BS = (BR + RD)/BR = 1 + SC/BS = RD/BR + 1

1 + SC/BS = 1 + RD/BR = SC/BS = 1 + BR/RD - 1

SC/BS = RD/BR

Inverting both sides

BR/RD = BS/SC

3) From BR/RD = BS/SC the above we have by cross multiplication;

BR/RD = BS/SC gives;

BR × SC = RD × BR → (BR)(SC) = (RD)(BR).

Find the greatest common factor of the following monomials 45m 6m^5
zzz [600]
The greatest common factor of 45m and 6m^5 is 3m. Here's how to find a greatest common factor:

1). Figure out the greatest number that divides evenly into every number in a given set. In your case, the number is 3.

2). Figure out the greatest number of variables that each of the monomials share. In your case, both of your monomials have at least 1 m. This can simply be represented as m. 

The final answer is the answers you get from steps 1 and 2 combined.

I hope this helps you out! I have a feeling that my wording might be confusing. If you have any questions, ask me as a comment.
