Grade: 6-a Lesson: S2-L3

Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Step	Type	Explanation	Answer
1	Problem	What is the complement of an angle whose measurement is 80 degrees?
2	Hint	Given angle, results in a sum of 90 degrees	A + B = 90°
3	Step	Given an angle whose measurement is 80°.
4	Step	Now plug the values	A + 80° = 90°
5	Step	Subtract 80° on both sides	A + 80° - 80° = 90° - 80°
6	Step	After simplification	A = 10°
7	Step	So, the complement of an angle with a measurement of 80 degrees is 10 degrees.
8	SumUp	Can you summarize what you’ve understood in the above steps?
9	Choice.A	This is not correct because it does not satisfy the definition of the complement	12 degree
10	Choice.B	This is not correct because it does not satisfy the definition of the complement	13 degree
11	Choice.C	This is correct as it represents the complement of the angle 80 degrees	10 degree
12	Choice.D	This is not correct because it does not satisfy the definition of the complement	18 degree

Problem

What is the complement of an angle whose measurement is 80 degrees?

Hint

Given angle, results in a sum of 90 degrees

A + B = 90°

Step

Given an angle whose measurement is 80°.

Step

Now plug the values

A + 80° = 90°

Step

Subtract 80° on both sides

A + 80° - 80° = 90° - 80°

Step

After simplification

A = 10°

Step

So, the complement of an angle with a measurement of 80 degrees is 10 degrees.

SumUp

Can you summarize what you’ve understood in the above steps?

Choice.A

This is not correct because it does not satisfy the definition of the complement

12 degree

Choice.B

This is not correct because it does not satisfy the definition of the complement

13 degree

Choice.C

This is correct as it represents the complement of the angle 80 degrees

10 degree

Choice.D

This is not correct because it does not satisfy the definition of the complement

18 degree
