All the others are 90 degrees too
Step-by-step explanation:
In a parallelogram opposite angles are congruent. Also in a quadrilateral the sum of angles is 360 degrees. since their are two pairs of congruent angles you could make an equation and it would look like this: 180+2x =360. x would be 90 making every angle 90 degrees.
Hope it helps :)❤

Answer:
67 pages in 1 hour
Step-by-step explanation:
A "unit rate" is a rate expressed with "one unit" in the denominator:
(201 pages)/(3 hours) = (201/3) pages/hour = (67 pages)/(1 hour)
Often, the unit of interest is a time unit. Here, it is 1 hour.
