Really could use some help

In triangles △ABC and △DEF, m∠A=m∠E, m∠C=m∠F, AC=6, EF=2, and AB=3.3, side

DF

is shorter than side

BC

by 3.2. Find the unknown sides of these triangles.

BC=4.8

DE=1.1

DF=1.6

Step-by-step explanation:

Since sides of similar triangles are proportional, I used this to calculate DE

Cross-multiply

To solve for BC and DF

BC-3.2=DE

Cross multiply

as -19.2 is transferred to the opposite side od the equation, its value becomes opposite aswell (negative to positive)

Simplify and divide both by 4

Since BC-3.2=DE, substitute BC with 4.8

i will pick c put check it over to be sure
