What facts are required in order to conclude that m∠ADE = m∠ABC?
mariarad [96]

Answer:

The correct option is;

DE = 2·(BC), AD = 2·(AB), and AE = 2·(AC)

Step-by-step explanation:

Given that we have;

1) The side AD of the angle m∠ADE corresponds to the side AB of the angle m∠ABC

2) The side DE of the angle m∠ADE corresponds to the side BC of the angle m∠ABC

3) The side AE of the angle m∠ADE corresponds to the side AC of the angle m∠ABC

Then when we have DE = 2·(BC), AD = 2·(AB), and AE = 2·(AC), we have by sin rule;

AE/(sin(m∠ADE)) = 2·(AC)/(sin(m∠ABC)) = AE/(sin(m∠ABC))

∴ (sin(m∠ADE)) = (sin(m∠ABC))

m∠ADE) = m∠ABC).

Find the missing side
lisabon 2012 [21]

Answer: 1) The missing length is 40.   2) The missing side is 30 .

Step-by-step explanation:

1)  9^2  + b^2 = 41^2

   81  +  b^2 = 1681

   -81                   -81

   b^2 =  1600

b= 40

2)  24^2 + 18^2 = c^2

 576  + 324 = c^2  

 900 =c^2

c= 30
