if two angles of a triangle add up to 110°, what is the measure of the third angle? (1 point)
check answer remaining attempts : 3

Explanation:

Step1: Recall the sum of angles in a triangle

The sum of the interior angles of a triangle is \(180^{\circ}\).

Step2: Calculate the third - angle

Let the sum of two angles be \(A = 110^{\circ}\). Let the third angle be \(x\). Using the formula \(A+x=180^{\circ}\), we can solve for \(x\) as \(x = 180^{\circ}-A\). Substituting \(A = 110^{\circ}\), we get \(x=180 - 110\).

Answer:

\(70\)
