### 3.1 (Day 2) Complement & Supplement Word Problems

Find the measure of a complement and/or supplement of an angle

Reminder
• Complementary angles have measures that add to _______
• Supplementary angles have measures that add to ________

180

Directions: For each example below, write an equation showing the relationship between the angles. Then solve the equation to find the value of x and the measure of each angle.

Ex 1: Complements Ex 2: Supplements

Directions: For each example below, write an equation showing the relationship between the angles. Then solve the equation to find the value of x and the measure of each angle.

Ex 3: Complements Ex 4: Supplements

Example showing “less than”

Which is 3 less than 10?

10-3 or 3-10

Where does “3 less than” go in an expression?

Directions: For each example below, write an equation showing the relationship between the angles. Then solve the equation to find the value of x and the measure of each angle.
