Angle Relationships and Problem Solving

Miss Harkness guides 8th-grade students through solving a word problem from Eureka Module 4, Lesson 5. The video covers decoding the problem, setting up equations, and solving them. Students are advised to use highlighters for better focus and are given a homework assignment. The lesson emphasizes reading the problem carefully, setting up a model, and using inverse operations to find the solution. The final steps include verifying the solution using a calculator.

Why is using a highlighter recommended when solving word problems?

• To make the paper look colorful

• To identify and focus on specific parts of the problem

• To draw attention to the teacher's notes

• To highlight the answers directly

What is the relationship between the two angles in the word problem?

• One angle is 13 less than five times the other

• The angles are equal

• One angle is 13 more than the other

• One angle is twice the other

What is the first step in setting up the model for solving the angle problem?

• Drawing two angles and labeling them

• Solving the equation directly

• Ignoring the word problem

• Guessing the values of the angles

How do you express angle A in terms of angle B?

• A = B - 13

• A = B + 13

• A = 5B - 13

• A = 5B + 13

What is the combined expression for the sum of the angles?

• 6B - 13

• 5B + B

• 5B - 13

• 6B + 13

What operation is used to isolate B in the equation 6B - 13 = 140?

• Multiplication

• Division

• Addition

• Subtraction

What is the value of angle B after solving the equation?

• 35

• 25.5

• 30

• 27.5

After finding B, what is the next step to find angle A?

• Subtract B from 140

• Multiply B by 5 and subtract 13

• Add 13 to B

• Divide B by 5

What is the final value of angle A?

• 140

• 127.5

• 153

• 114.5

How can you verify the solution for angles A and B?

• By checking if their sum is 140

• By checking if A is 13 more than B

• By checking if B is 13 less than A

• By checking if A is 5 times B
