Can someone please help!

Step-by-step explanation:

1) AD = DC                    Given

∠A = ∠C    

2) ∠ADE = ∠CDF         Vertically opposite angles

3) ΔADE ≅ ΔCDF           Angle side Angle congruent ( A S A congruent}

angle EDA congruent to angle FDC because vertical angles

Trangle ADE is congruent to CDF because ASA congruence

Step-by-step explanation:

angle EDA will always be congruent to angle FDC cause they're made up of the same lines forming 2 angles (vertical angles)

and then you have 2 angles as one side which is enough to prove they're congruent and the proved angles/sides are in the order Angle Side Angle (ASA)

probably didn't make sense but hope it did

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
