What are the angles of M N and P

ANSWER:
M = 37 degrees
N = 84 degrees
P = 59 degrees

Rule: Three interior angles of a triangle add up to 180.

Step 1: FIND ‘X’)

M + N + P = 180
4x - 3 + 9x - 6 + 6x - 1 = 180
19x - 10 = 180
19x = 190
x = 10

Step 2: SUBSTITUTE ‘X’ INTO EACH ANGLE EQUATION)
M = 4(10) - 3
= 40 - 3
M = 37

N = 9(10) - 6
= 90 - 6
N = 84

P = 6(10) - 1
= 60 - 1
P = 59

How many people are we starting with? i will answer it's just i need to divide 8 by the total amount of people to get how many tables

I’m having a hard time understanding your question
