Solve 10-13 find each measurement

10)17.5

11)18

12)70

13)110

Problem 10

This is because the opposite sides of any parallelogram are congruent (PQ = RS and QR = PS)

Problem 11

Diagonal QS is cut in half (bisected) by the other diagonal PR. The smaller pieces QT and ST are the same length.

Problem 12

The angle QRS is given to be 110 degrees. Angle PQR adds to this to get 180, so we effectively solve x+110 = 180 to get x = 70. Any pair of adjacent angles of any parallelogram are supplementary.

Problem 13

Opposite angles of a parallelogram are congruent. Angle SPQ is opposite of angle QRS = 110.

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
