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 interior angles of a triangle is 180°. So, $(s - 22)+81 + 34=180$.

Step2: Simplify the left - hand side

$(s-22)+81 + 34=s+( - 22+81 + 34)=s + 93$.

Step3: Solve for s

We have the equation $s + 93=180$. Subtract 93 from both sides: $s=180 - 93$. So, $s = 137$.

Answer:

137
