Question

the diagram shows a triangle.
what is the value of s?
s = \square^\circ

Explanation:

Step1: Sum angles to 180°

$(2s+2) + (3s+3) + (s+13) = 180$

Step2: Combine like terms

$2s+3s+s + 2+3+13 = 180$
$6s + 18 = 180$

Step3: Isolate the variable term

$6s = 180 - 18$
$6s = 162$

Step4: Solve for s

$s = \frac{162}{6}$

Answer:

$s = 27$
