PQRS is a parallelogram find each measure

In a convex quadrilateral, each of the four angles, i.e., ∠QPS, ∠PQR, ∠QRS and ∠RSP as in figure (i), is less than 180°. ..Parallelogram: A quadrilateral whose opposite sides are parallel, is called a parallelogram. In the given figure PQRS is a parallelogram in which PQ ∥ SR and PS ∥ QR.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !
