138° + w° = 180° (sum of angle on a straight line)
w° = 180° - 138°
w = 42
19° + x° + w° = 90°
sub. in w=42,
19° + x° + 42° = 90°
x° = 90° - 19° - 42°
x° = 29°
x = 29
Answer: B. YesStep-by-step explanation:We have been given that in parallelogram ABCD, D is a right angle. We are asked to determine whether the given parallelogram is rectangle or not.Let us recall parallelogram properties.Opposite angles of parallelogram are equal.Consecutive angles of parallelogram are supplementary.Since D is a right angle, so its opposite angle will be right angle as well and consecutive angles of angle D will be right angles as well.Therefore, the parallelogram ABCD is a rectangle and option B is the correct choice.

Answer:
14 socks.
Step-by-step explanation:
3 1/2 / 1/4
= 7/2 / 1/4
= 7/2 * 4
= 28/2
= 14 socks.
5.3/8.8=x/14.3
AB is x,
x= 2.43
