If two angles of a triangle add up to 110°

, what is the measure of the third angle?

1 answer

The sum of all angles of a triangle is always 180°.

Let's denote the measure of the third angle as x.

According to the given information, we have:

x + 110° = 180°

We can now solve for x:

x + 110° - 110° = 180° - 110°

x = 70°

Therefore, the measure of the third angle is 70°.
