PLEASE HELP MATH AND FIND THE VALUE OF X

x = 10°

Step-by-step explanation:

99° + 3x + 12° + 39° = 180° {Being sum of angles of triangle }

150° + 3x = 180°

3x = 180° - 150°

3x = 30°

x = 30°/ 3

x = 10°

Hope it will help :)❤

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
