Vertex angle = x
1 base angle = 1/2x - 8
180-x = (1/2x-8)x2
180-x = x-16
196-x = x
196 = 2x
x=98
If you want explanation please ask me .
If you want to know what is the number of m so first you can add 2 on both sides of equation like : 13 = 5m - 2
+2 +2 ⇒ 13 + 2 = 5m ⇒ 15 = 5m ⇒ 15/5 = m ⇒ 3=m :))
i hope this be helpful
have a nice day
