Question

solve for the value of s.
answer attempt 1 out of 2

Explanation:

Step1: Note angle - sum property

The sum of the three angles is 180° since they form a straight - line. So, $(2s + 2)+90+(3s - 2)=180$.

Step2: Simplify the left - hand side

Combine like terms: $(2s+3s)+(2 - 2)+90 = 180$, which simplifies to $5s+90 = 180$.

Step3: Isolate the variable term

Subtract 90 from both sides: $5s+90−90 = 180−90$, resulting in $5s=90$.

Step4: Solve for s

Divide both sides by 5: $\frac{5s}{5}=\frac{90}{5}$, so $s = 18$.

Answer:

18
