Answer:

A...similar triangles

Step-by-step explanation:

option b... the two triangles are not congruent

option c... the area of ∆AED= 3, ∆ACB= 12.. half of 12 is 6.. wrong

option d. perimeter of ∆AED= 8.60, area of ∆ACB = 12... one fouth of 12 =3. wrong.

option A.. similar triangles have the same shape but they necessarily don't need to have the same size. ... correct! both triangles are right angled triangles.

note.. perimeter is summation of all sides..

solving unknown side use Pythagoras formulae

Adam plans to choose a video game from a section of the store where everything is 75%
Minchanka [31]

Answer:

Look below

Step-by-step explanation:

In Adam's expression, d represents the original price of the game. 0.75d represents 75% of the original price; this is the amount of the discount, since everything is 75% off.  Taking the difference of the original price and the discount, d-0.75d, gives us the total price of the game. In Rena's expression, 0.25 represents 25%.  This is because taking 75% off of the price means we still pay 100-75 = 25% of the original price. Multiplying the original price, d, by the 0.25, gives us 25% of the original price; this is the total price.
