finddddd the value of x

Answer:
1)x = 30°
2) x = 46°
3) x = 20°
4)x = 53°
Step-by-step explanation:
The sum of all three angles of a triangle is 180°.
1) x + 60 + 90 = 180
x + 150 = 180
x = 180 - 150
[tex]\sf \boxed{\bf x = 30^\circ}[/tex]
2) 57 + 77 + x = 180
134 + x = 180
x = 180 - 134
[tex]\sf \boxed{\bf x = 46^\circ }[/tex]
3) 134 + 26 + x = 180
160 + x = 180
x = 180 - 160
[tex]\sf \boxed{\bf x = 20^\circ}[/tex]
4) 65 + 62 + x = 180
127 + x = 180
x = 180 - 127
[tex]\sf \boxed{x = 53^\circ}[/tex]
