Question

what is the value of s? u s 100° v t s = °

Explanation:

Step1: Recall the property of isosceles triangle

In an isosceles triangle, the sum of interior angles is \(180^{\circ}\).

Step2: Set up the equation

Let \(s\) be one of the equal angles. The equation is \(s + s+ 100^{\circ}=180^{\circ}\).

Step3: Solve the equation

Combine like terms: \(2s=180^{\circ}- 100^{\circ}\), so \(2s = 80^{\circ}\). Then \(s=\frac{80^{\circ}}{2}\).

Answer:

\(40\)
