Question A & Question B

Answer 1

Explanation:

If the arrows in the segments [AB] and [DE] means that the lines (AB) and (DE) are parallele than

we use the dilation of center C which image of

D is A

E is B

has for ratio 5/2=2.5.

A) The image of the triangle CDE is the triangle CAB which are similar.

B)

`(CE)/(CB) =(DE)/(AB) \\\\==>\ (3)/(3+y) =(2)/(5)\\\\==>\ 6+2y=15\\\\==>\ 2y=9\\\\\\==>\ y=(9)/(2) \\\\\\The\ image\ of\ \widehat{CDE}=\widehat{CAB}\ ==>\ x=48^o\\\\`
