Answer:
ASA postulate of congruency
Step-by-step explanation:
Here Given AE=ED and ∠BAE=∠CDE
Also if we clearly observe ∠AEB=∠CED
By ASA postulate those two triangles are congruent.
The ASA (Angle,Side,Angle) postulate states that if two triangles with two angles and the included angle are equal then the two triangles are congruent.
Answer:
8:45
Step-by-step explanation:
279 divided by 62 is 4.5
4.5 hours or 4 hours and 30 min plus 45 min break is 5 hours and 15 min
so need to leave by 8:45
<u>B) </u>
<u>C) </u> volume =
.
<u>Step-by-step explanation:</u>
Here we have , The base of an open rectangular box is of length (2x+5) cm and width x cm. The area of this base is 58cm^2. The height of the open box is (x-2) cm. We need to find the following :
a) show that 2x^2+5x-58=0
We know that area of rectangle = 
⇒ 
Putting values according to question we get :
⇒ 
⇒ 
⇒ 
b) solve the equation in the question above, giving your answer to 2 decimal places
Solving this equation :
⇒ 
By quadratic formula
⇒ 
⇒ 
⇒ 
⇒
{ Since side can't be negative ! }
⇒ 
c) calculate the volume of the box, stating units of you answer
Since x = 4.28 , other sides are

We know that volume is given by :
⇒ 
⇒ 
⇒ 
Therefore , volume =
.
4(2y−9) is the correct answer
Y= 55 degrees is the answer good luck
