Regina is trying to figure out if ΔABC and ΔDEF
are congruent. She already knows that AC¯¯¯¯¯¯¯¯
is the same length as DF¯¯¯¯¯¯¯¯
, and ∠A
is the same measure as ∠D
.
Jared tells her that if ∠B
and ∠E
are the same measure, she’ll know the triangles are congruent.

Isaac tells her that if BC¯¯¯¯¯¯¯¯
and EF¯¯¯¯¯¯¯¯
are the same length, she’ll know the triangles are congruent.
Who is correct?

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be

you have 6 equal triangles, find the area of one of them (b*h/2) and multiply by 6

(8*4: 2)*6 =

32 cm² is your answer

if i did my math right then the answer should but 108
