It means that when you have s=4, or the length of one of the sides of the cube is 4, then the volume is 64 cubic units
Exterior Angles Theorem is used.
The exterior angle of a triangle is equal to the 2 opposite interior angles.
Therefore, 65+78=143°, since 65 and 78 are the 2 opposite interior angles.
So, the answer is 143°
I think it’s A sorry if I’m wrong
Answer:
it would be 14

12-2= 10
10+5= 15
Hope this helps
