Answer:
m<1 = 127°
Step-by-step explanation:
Vertical Opposite angles are always equal .
So as <1 & <2 are vertically opposite angles ,
m<1 = m<2
It's given that m<1 = 5x + 12 & m<2 = (6x - 11)
So ,
[tex]5x + 12 = 6x - 11[/tex]
[tex] = > 6x - 5x = 12 + 11[/tex]
[tex] = > x = 23[/tex]
As the value of x = 23 , m<1 = 5x + 12
= 5×23 + 12
= 115 + 12
= 127°
