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 angles in a triangle is always 180 degrees.

Let's call the measure of the third angle x degrees.

So we have the equation: x + (angle 1) + (angle 2) = 180

But we are given that (angle 1) + (angle 2) = 110.

So we can substitute this value into the equation: x + 110 = 180

To isolate x, we subtract 110 from both sides: x = 180 - 110

Simplifying, we find: x = 70

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