Answer:
55°
Step-by-step explanation:
If one unknown angles of triangle is X
[tex]70 + 2x = 180[/tex]
[tex]2x = 180 - 70 = 110[/tex]
[tex]x = 110 \div 2 = 55[/tex]

Answer:
let 2 angles of triangle be x
by angle sum property we know that sum of 3sides of angle = 180 degree
so,
2x + 70 = 180
2x = 180 - 70
2x = 110
x = 110 / 2
x = 55 degree
