Find the value of x in the triangle shown below

As to sidea are equal therefore it is an isosceles triangle .

therefore

,80+x+x=180

80+2x=180

2x=100

x=50

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)
