Question

find the number of degrees in the third angle of the triangle. the measure of the missing angle is (square^{circ})

Explanation:

Step1: Recall angle - sum property

The sum of the interior angles of a triangle is 180°. Let the three angles of the triangle be \(A = 44^{\circ}\), \(B=91^{\circ}\), and \(C\) (the missing angle). Then \(A + B + C=180^{\circ}\).

Step2: Solve for the missing angle

We can rewrite the equation as \(C = 180^{\circ}-A - B\). Substitute \(A = 44^{\circ}\) and \(B = 91^{\circ}\) into the equation: \(C=180-(44 + 91)\). First, calculate \(44+91 = 135\). Then \(C=180 - 135=45^{\circ}\).

Answer:

45
