Hello my friend it's easy to find.....
let me say that method!!!!!!
Total angle of the triangle is 180
so we have to add the both sides which u known already.......
with the last answer u have to subtract with 180
for ex:
if two sides are 60,60,x(the unknown side)
60+60+x=180
120+x=180
x=180-120
x=60
hope it helped
pls mark as brainliest

Let us assume
First angle = x = 30
Second angle = y = 50
Third angle = z = ?
X + Y + Z = 180
30 + 50 + Z = 180
80 + Z = 180
Z = 180-80
Z =100
