The angle between u = (-2,-5) and v = (5,2) is 134 degrees approximately.
<u>Solution:</u>
Given, two vectors are u = (-2, -5) and v = (5, 2)
We have to find the angle between two vectors.
We know that,
where 
is angle between vectors a and b
Hence, the angle between given two vectors is 134 degrees approximately.
A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity classes II and III.
