Question

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 what is the measure of the third angle

Answer 1

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°
