In Exercises $13-18,$ determine whether the two vectors are orthogonal and, if not, whether the angle between them is acute or obtuse.$$\left\langle\frac{12}{5},-\frac{4}{5}\right\rangle, \quad\left\langle\frac{1}{2},-\frac{7}{4}\right\rangle$$

So, first, let’s make sure i have the proper definitions of certain angles. So what is a vertical angle? Vertical angles are when i have 2 lines that cross and they are directly across from each other. So an example of a vertical angle could be angle 4 angle. To it, there 2 lines that are exactly across and they’re going to be equal or 1 and 3 are vertical angles. Angle 1 is congrued to angle 3 because they are across from 2 lines that are crossing. What is a…
