The sum of angles in a triangle is always 180°. So, let’s call the third angle x.
We know that:
40° + 70° + x = 180°
Simplifying the equation:
110° + x = 180°
Subtracting 110° from both sides:
x = 70°
Therefore, the third angle measures 70°.
We know that:
40° + 70° + x = 180°
Simplifying the equation:
110° + x = 180°
Subtracting 110° from both sides:
x = 70°
Therefore, the third angle measures 70°.
