Question

the diagram shows a triangle. what is the value of s? s = □°

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°.

Step2: Set up an equation

Let the three angles of the triangle be 41°, 38°, and s. So, 41 + 38+ s=180.

Step3: Simplify the left - hand side of the equation

41 + 38 = 79, so the equation becomes 79 + s=180.

Step4: Solve for s

Subtract 79 from both sides of the equation: s=180 - 79.
s = 101.

Answer:

101
