These triangles are similar. find Y and X

Answers

Answer 1

Answer:

It these triangles are similar, then the sides of the triangles are in proportion:

$(y)/(10)=(y+4)/(15)$ cross multiply

$15y=10(y+4)$ use distributive property

$15y=10y+40$ subtract 10y from both sides

$5y=40$ divide both sides by 5

$\boxed{y=8}$

$(x)/(4)=(6)/(8)$ cross multiply

$8x=(4)(6)$

$8x=24$ divide both sides by 8

$\boxed{x=3}$
