Two adjacent angles of a paralle
logram are congruent. What is the measure of
each?

​

Each would need to have a size of . In other words, these two angles are both right angles, and this parallelogram would also be a rectangle.

Step-by-step explanation:

Two angles that congruent have the same size.

At the same time, those two adjacent angles of this parallelogram would be a pair of consecutive interior angles. Because the two sides of a parallelogram are parallel to one another, the sum of these two consecutive interior angles would be - they are supplementary to one another.

Let the two angles be and .

because the two angles are congruent.

because these two angles are adjacent angles of a parallelogram.

Hence, .

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

the answer is 13 cm
