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

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
