If abc ~ def, what is the scale factor of abc to def? triangle abc has angles of 18, 21, 24. triangle def has angles of ? , 7, ?

3/1

Step-by-step explanation:

Using the similarity statement, ∠A corresponds with ∠D; ∠B corresponds with ∠E; and ∠C corresponds with ∠F.

The only angle of triangle DEF we have is ∠E, which is 7.  This corresponds with ∠B; this makes the scale factor of ABC to DEF

21/7 = 3/1.

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
