The measure of the third angle is 65°
Step-by-step explanation:
Each lapel on a suit jacket is in the shape of a triangle
- Two of the three angles of each triangle measures 47 and 68
- We need to find the measure of the third angle
In a triangle:
∵ The sum of the measures of the interior angles = 180°
∵ The measure of one angle = 47°
∵ The measure of other angle = 68°
- Substitute the measures of the two angles in the rule above
∴ 47 + 68 + measure 3rd angle = 180°
- Add the like terms
∴ 115 + measure 3rd angle = 180°
- Subtract 115 from both sides
∴ measure 3rd angle = 65°
The measure of the third angle is 65°
