Answer:
.
Step-by-step explanation:
Given:
![\angle BDC = 31\°](https://tex.z-dn.net/?f=%5Cangle%20BDC%20%3D%2031%5C%C2%B0)
We need to find
.
Solution:
Now we can see that given figure is a rectangle with diagonals drawn in it.
So by properties of rectangle which states that;
"All angles of a rectangle are 90°."
So we can say that;
![\angle A = \angle B = \angle C = \angle D = 90\°](https://tex.z-dn.net/?f=%5Cangle%20A%20%3D%20%5Cangle%20B%20%3D%20%5Cangle%20C%20%3D%20%5Cangle%20D%20%3D%2090%5C%C2%B0)
But
![\angle D = \angle BDC + \angle ADB](https://tex.z-dn.net/?f=%5Cangle%20D%20%3D%20%5Cangle%20BDC%20%2B%20%5Cangle%20ADB)
Substituting the values we get;
![31\°+\angle ADB = 90\°](https://tex.z-dn.net/?f=31%5C%C2%B0%2B%5Cangle%20ADB%20%3D%2090%5C%C2%B0)
Subtracting both side by by 31 we get;
![31\°+\angle ADB -31\°= 90\°-31\°\\\\m\angle ADB = 59\°](https://tex.z-dn.net/?f=31%5C%C2%B0%2B%5Cangle%20ADB%20-31%5C%C2%B0%3D%2090%5C%C2%B0-31%5C%C2%B0%5C%5C%5C%5Cm%5Cangle%20ADB%20%3D%2059%5C%C2%B0)
Hence

You didn't show the examples so I can't really say anything
The answer is 5.5 because you have to put all of the numbers in numerical order 1 2 3 5 5 6 7 9 9 14 then find the two middle numbers and add them and you get 11. Divide 11 by two and get 5.5.
Step-by-step explanation:
two vertical vectors one with upward direction and 150 units and one with downward direction of 120 units,
the resultant of the vectors = 150-120 = 30 units
with upward direction.
The answer is 117.5 because to find the interquartile range first u need to find the median. Then you fave to find the lower quartile which is 125 and thenearest u need to find the upper quartile which is 242.5. Finally u subtract 242.5 by 125 to get 117.5.
Hope it helped
