conditions for parallelograms
for each definition or theorem, tell what information you would
need about the figure to conclude that the figure is a parallelogram.
for some exercises, there is more than one correct answer, but give
only one example per exercise.
1. if both pairs of opposite angles of a quadrilateral are
congruent then the quadrilateral is a parallelogram.
if both pairs of opposite sides of a quadrilateral are

what is the answer?

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

ion

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
