Question

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

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is \(180^\circ\). So, \(30^\circ + 33^\circ + 1.3s = 180^\circ\).

Step2: Simplify the equation

First, add \(30\) and \(33\): \(63^\circ + 1.3s = 180^\circ\).
Then, subtract \(63\) from both sides: \(1.3s = 180 - 63 = 117\).

Step3: Solve for \(s\)

Divide both sides by \(1.3\): \(s=\frac{117}{1.3}=90\).

Answer:

\(s = 90\)
