The correct answer is: Opposite angles of a parallelogram are congruent.
In a parallelogram, the opposite angles are always congruent. The opposite angles are the angles diagonal across from each other.
You can tell by the order of ABCD that A and C are opposite. B and D are also opposite of each other and congruent.
Width = 45 inches
Height = 36 inches
Area = 45 • 36 = 1620 inches squared
Answer:
0.13 hours
468 seconds
Step-by-step explanation:
7.8 min= 7.8/60= 0.13 hours
7.8 min= 7.8x60= 468 seconds
Answer:
54 degrees
Step-by-step explanation:
This is trigonometry. So we are given the adjacent leg and hypotenuse. So we can use cosine(cah from soh cah toa)
We will have to use the inverse of the trig ratios.
Remember!
cos^-1 is not 1/cos(that is sec)
cos^-1(27/46)
acos(27/46)
54.0586701 and so on
Round to nearest degree 54
