all angles in a triangle add up to 180. try to create an equation with angles 2, 3, and 4 that adds up to 180 |dw:1435412801948:dw|

OpenStudy (abdullahm):

What is the sum of all the angles in a triangle?

OpenStudy (anonymous):

@AbdullahM 180

OpenStudy (abdullahm):

so make an equation where the sum of angles 2, 3, and 4 are added and equal to 180

OpenStudy (abdullahm):

and solve for x.

OpenStudy (anonymous):

\[x+40+5x+14=180\]

OpenStudy (abdullahm):

good job, and solve for x now :)
