Use the figure to answer the questions.

Part A. Explain why the triangles are similar.

Triangle ___ and Triangle___ are similar by the _ postulate. This postulate works because...
(explain your reasoning here)

Part B. Find the value of y.
(show your work)

Please help! Thank you so much I appreciate it!

a) Triangle ABE is similar to Triangle DCE by Angle-Angle-Angle postulate.

b) 4 cm

Step-by-step explanation:

a) angle A = angle D

And

angle B = angle C

(Alternate angles)

Angle AEB = Angle DEC

(Vertically opposite angles)

All three angles are equal, hence triangles are similar

b)

AB/DC = AE/DE

6/15 = y/10

y = 6×10/15

y = 4

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
