Answer:

Option A is correct that is Required additional information is ∠BDC and ∠AED are right angles.

Step-by-step explanation:

We need to find an additional information used to to prove ΔCEA ~ ΔCDB

In ΔCEA and  ΔCDB

    ∠ACE = ∠BCD  ( common angle in both triangle )

if,  ∠AEC = ∠BDC  ( both are right angles )

then ΔCEA ~ ΔCDB by AA similarity criteria.

Therefore, Option A is correct that is Required additional information is ∠BDC and ∠AED are right angles.

Oliga [24]
To find the value of x we need to use the INVERSE OPERATION of addition which is subtraction. Then we will check our work. lets do it:- 

x + 19 = 13
x = ?
13 - 19 = x 
<span>13 - 19 = -6</span>
x = - 6

CHECK OUR WORK:-
 
x + 19 = 13
x = -6
-6 + 19 = 13 
We were RIGHT!!

So, x = -6

Hope I helped ya!! xD

1/y - 1/x = 1/60<br> 3y - 2x = 6 <br> (Simultaneous question)
Daniel [21]

1y - 1/x = 1/60 = x*y =60 = x=60/y

3y - 2(60/y) = 6

3y^2-120=6y

3(y^2-40-2y) =0

y^2-40-2y=0

y = 7.4


3(7.4)-2x=6

22.2-2x = 6

2x = -16.2

x = -8.1
