Question

the angles in the figure below form a straight angle. write an equation to represent the relationship between the angles in the figure. 65° b° 20°

Explanation:

Step1: Recall the measure of a straight angle

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

Step2: Set up the equation

The sum of the three angles (\(65^{\circ}\), \(b^{\circ}\), and \(20^{\circ}\)) is equal to \(180^{\circ}\). So the equation is \(65 + b+ 20=180\).

Answer:

\(65 + b + 20=180\)
