The sum of all angles of a triangle is 180 degrees
OpenStudy (agent47):
Thus: x+30+75=180, or x+105=180 x = 180-105
OpenStudy (agent47):
im sure u can finish the rest
OpenStudy (anonymous):
ahh Thank you so much, so basically all i do is add the two angles and then subtract by 180?
OpenStudy (agent47):
yea, add the two known angles, and then subtract the sum from 180 to get the answer
