Question

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

Answer 1

In a triangle, the sum of all three angles is always equal to 180°. Given that two angles add up to 110°, we can find the measure of the third angle by subtracting the sum of the two known angles from 180°.

Step-by-step explanation:

In a triangle, the sum of all three angles is always equal to 180°.

Let's say the measure of the third angle is x°.

Given that two angles add up to 110°, we can write the equation: x + 110° = 180°

Solving for x gives us x = 70°.

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