Irrational because square root of 15 is irrational
The answer is 7 because f is a denomination
I think those are coordinates of points, (-5,8) and (-2,8)
so you just need to use distance formula ((8-8)^2+(-2+5)^2)=0+9=9
square root 9=3
Looking at the angles of the triangles
N=S
M=R
O=T
so MON would be RTS
I don’t know this one either bro
