Question

15 multiple choice 1 point a triangle has angles measurements of 23 and 35 degrees. what is the measure of the third angle? 180 32 122 90

Explanation:

Step1: Recall the sum of angles in a triangle

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

Step2: Set up the equation

Let the third - angle be \(x\). Then \(x + 23+35=180\).

Step3: Solve for \(x\)

First, simplify the left - hand side: \(x+(23 + 35)=x + 58\).
The equation becomes \(x+58 = 180\).
Subtract 58 from both sides: \(x=180 - 58\).
\(x = 122\).

Answer:

C. 122
