ΔADC ≅ ΔBCD (SAS theorem)

∠AED ≅ ∠BEC (opposite angles )

ΔAED ≅ ΔBEC (ASA congruency postulate)

Therefore DE ≅ CE (CPCTC: Corresponding Parts of a Congruent Triangle are congruent)

hope this helps

True or False? Shapes that have no right angles also have no perpendicular segments.

I think this is True. Because Perpendiculer Lines Rely On Right Angles. :)

Total cost for cookie and lemonade is 1.80. If lemonade costs 1.00 more than the cookie, how much was the lemonade?
Ray Of Light [21]

Answer:

The lemonade costs 1.4.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x is the cost of a cookie.

y is the cost of a lemonade.

Total cost for cookie and lemonade is 1.80.

This means that x + y = 1.8.

As we want y, we have that x = 1.8 - y

Lemonade costs 1.00 more than the cookie?

This means that:

y = x + 1

So

y = 1.8 - y + 1

2y = 2.8

y = \frac{2.8}{2}

y = 1.4

The lemonade costs 1.4.
