Add the three angles and set them to 180
4x-13+15+x+18=180
5x+20=180
5x=160
x=32
Then plug in to get A and C
A=4*32-13
A=115
C=32+18
C=50
Find u, v , u , v , and d(u, v) for the given inner product defined on Rn. u = (0, −4), v = (5, 3), u, v = 3u1v1 + u2v2

Answer:


Step-by-step explanation:
We are given that inner product defined on 

u=(0,-4),v=(5,3)
We have to find the value of <u,v> and d(u,v)
We have 
Substitute the value then we get

Now, 
Using this formula we get
