  1. 4-4 Lesson 4-4 Example 5 Solve. CAMPING The entry to Ayame’s tent is in the shape of a triangle. It has a 104° angle and a 38° angle. What is the measure of the third angle of the tent entrance?

  2. 4-4 Lesson 4-4 Example 5 Understand Read the problem. Write what you know. The measure of one angle of the tent’s entrance is 104°. The measure of the other angle is 38°.

  3. 4-4 Lesson 4-4 Example 5 Plan Pick a strategy. One strategy is to draw a diagram.

  4. 4-4 Lesson 4-4 Example 5 Solve Find the sum of the measures of the known angles. 104°+ 38°= 142° Subtract this sum from 180°. 180°– 142°= 38° The measure of the third angle is 38°.

  5. 4-4 Lesson 4-4 Example 5 Check Add the three angle measures. The sum should equal 180°. 104°+ 38°+ 38°= 180°
