Question

the angles in the figure below form a straight angle. write an equation to represent the relationship between these angles. a + 100 + a = 180

Explanation:

Step1: Recall the property of a straight - angle

A straight - angle measures \(180^{\circ}\).

Step2: Analyze the given angles

The three angles in the figure are \(a^{\circ}\), \(100^{\circ}\), and \(a^{\circ}\). Their sum is equal to the measure of the straight - angle.

Answer:

\(a + 100+a=180\)
