Find the measure of the numbered angles for each parallelogram

Step-by-step explanation:

∠1 + 85 = 180  {linear pair}

∠1 = 180 -85

∠1  = 95

∠1 +∠2 + 48 = 180 {Angle sum property of triangle}

95 + ∠2 + 48  = 180

       ∠2          = 180 - 95 - 48

               ∠2 = 37

∠3 = ∠2         {Alternate angles are congruent}

∠3 = 37

FIRST BOX IS 4

SECOND BOX IS 3

THIRD BOX IS 5

FOURTH BOX IS 2

Step-by-step explanation:

(4x-3)(3x+5)=12x^2- 2x-15
