Answer:
books.
Step-by-step explanation:
We have been given that Hannah's school hosted a book donation.
Total number of students = 150.
Total number of books donated by all students = b.
Since we know that average is calculated by dividing the sum of the values in the set by their number.
Since we are told that Hannah donated 3 times as many as the average number of books each student donated. So books donated by Hannah will be:
Upon simplifying we will get,
Therefore, Hannah donated books.
These words are point, line and plane, and are referred to as the "three undefined terms of geometry.
They are undefined because they cannot be defined by using other figures.
Answer:
ACB = 112°
Step-by-step explanation:
First form a sketch where will have a triangle sketch showing the points ABC with AB= 80km and CB = 56 km
Apply the law of cosine as;
c²=a²+b²-2ab*cos(C)
To get angle C;
C=arccos((a²+b²-c²)/(2ab))
Substitute values given in the equation as
C=arccos((40²+56²-80²)/(2*40*56))
C=arccos(-1664/4480)
C=112°
