In ΔDCE + ΔGFH,
∠C = ∠F (given)
∠D = ∠C (angle sum of a triangle)
∠H = ∠E (angle sum of a triangle)
∴ ΔDCE is similar to ΔGFH
Hope this helps!
Answer:
.2
Step-by-step explanation:
When you do 64/80 you get 0.8 which means that the percent decrease is .2
Yes you have a good example.
x = number of cookies
2*x = total amount spent on cookies at $2 each
2x-3 = amount you pay after the $3 discount is applied one time for the entire order
-------------
a more numeric example may be this
Lets say you bought 12 cookies, so x = 12
This means it costs 2*x = 2*12 = 24 dollars total if the discount doesnt apply
However, the 3 dollar discount is there, so the grand total is 24-3 = 21 dollars.
Answer:
JL = 54
Step-by-step explanation:
JL = JK + KL
JK = KL
8x+11 =14x-1
12 = 6x
x = 2
substitute for x:
8(2)+11 + 14(2)-1 = JL
JL = 16+11+28-1
JL = 54
