Answer:
x = 15
Step-by-step explanation:
Similar triangles and proportional side lengths.
10/4 = x/6
5/2 = x/6
2x = 5 * 6
2x = 30
x = 15

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
