Answer:
o = 54
Step-by-step explanation:
The angle sum theorem tells you the sum of angles in a triangle is 180°. The definition of a linear pair tells you the two angles of a linear pair total 180°. Together, these relations tell you that an exterior angle of a triangle is equal to the sum of the remote interior angles.
In this geometry, the angle marked 78° is exterior to the left-side triangle. That means ...
78° = o° +24°
o° = 78° -24° = 54°
The value of 'o' is 54.

<em>Additional comment</em>
n° is the supplement of 78°, so is 102°.
m° is the difference between 102° and 22°, so is 80°.
Solution: The number of ways we can arrange 3 blue marbles if a set of 5 marbles is selected is:
![\binom{5}{3}=\frac{5!}{(5-3)!3!}](https://tex.z-dn.net/?f=%5Cbinom%7B5%7D%7B3%7D%3D%5Cfrac%7B5%21%7D%7B%285-3%29%213%21%7D)
![=\frac{120}{2 \times 6}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B120%7D%7B2%20%5Ctimes%206%7D)
![=\frac{120}{12}=10](https://tex.z-dn.net/?f=%3D%5Cfrac%7B120%7D%7B12%7D%3D10)
Therefore, there are 10 ways we could arrange 3 blue marbles.
A= 9000m squared and A= base(width)*hight or A=b*h so divide 9000m by 60m
9000/60=(1050) 60 120 180 240 300 360 420 480 and so on
1 2 3 4 5 6 7 8
