Q. Megan drew two angles. The measure of the smaller angle is 13∘ less than the measure of the bigger angle. The measure of the smaller angle is 79∘. Let b represent the measure of the bigger angle. Which equation models the problem?Choices:(A) b−13=79(B) 13+b=79Solve this equation to find the measure of the bigger angle.____∘
Understand relationship between angles: Step 1: Understand the relationship between the angles. The smaller angle is 13∘ less than the bigger angle, and it measures 79∘. So, the equation should show the bigger angle minus 13 equals the smaller angle.
Identify correct equation: Step 2: Identify the correct equation from the choices. The correct equation that models this relationship is (A)b−13=79, because it correctly shows the bigger angle minus 13 equals the smaller angle.
Solve equation: Step 3: Solve the equation b−13=79. Add 13 to both sides to isolate b: b−13+13=79+13, which simplifies to b=92.
