Answer:
AB = 3 and AC = 4
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
30AB = 90 ( divide both sides by 30 )
AB = 3
and
= , substitute values
= ( cross- multiply )
30AC = 120 ( divide both sides by 30 )
AC = 4
