Calculate the distance between the points P =(-5, 4) and N =(2, 4) in the coordinate plane,
Give an exact answer (not a decimal approximation),

entering that problem on the tube might get you an answer

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
