Question

46th 50 0 bonus 10/10 find the measure of each angle indicated. 75°? 39° 139° 66° 138° 116°

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is \(180^\circ\).

Step2: Calculate the unknown angle

Let the unknown angle be \(x\). Then \(x + 75^\circ + 39^\circ = 180^\circ\). Solve for \(x\): \(x = 180^\circ - 75^\circ - 39^\circ = 66^\circ\).

Answer:

66° (corresponding to the option with 66°)
