Answer:
x = 26, y = 19
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
= 2 ( multiply both sides by 13 )
x = 26
and
=
, substitute values
=
=
( cross- multiply )
2y = 38 ( divide both sides by 2 )
y = 19
6C2 = 6*5*4*3*2 /2*4*3*2 = 720/48 = 15
