x = 6 , y = 3.5
Explanation:
since the triangles are similar then the ratios of corresponding sides are in proportion , that is
=
( substitute values )
=
( cross- multiply )
8x = 12 × 4 = 48 ( divide both sides by 8 )
x = 6
and
=
( substitute values )
=
( cross- multiply )
8y = 7 × 4 = 28 ( divide both sides by 8 )
y =
= 3.5
