Question

If two angles of a triangle add up to 110° , what is the measure of the third angle?

Answer 1

The sum of the three angles in a triangle is always 180°. Let's call the measure of the third angle x. We know that two angles add up to 110°, so we can write the equation:

x + 110° = 180°

To find x, we need to isolate it on one side of the equation. Subtract 110° from both sides:

x = 180° - 110°

x = 70°

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