Find the value of x.

x=27

Step-by-step explanation:

132 + 21 = 153

180 - 153 = 27

The inside of a triangle always equals 180 and you have angles 132 and 21. In total it's 153. Subtract 180 - 153 and you get 27.

x = 27

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)
