Answer :
To find the measure of the third angle in a triangle where two angles are given as 62° and 15°, follow these steps:
1. Recall the sum of angles in a triangle:
The sum of the interior angles in any triangle is always 180°.
2. Add the given angles together:
Add the measures of the two known angles:
[tex]\[ 62° + 15° = 77° \][/tex]
3. Subtract the sum of the known angles from the total sum:
Subtract the sum of these two angles from 180° to find the measure of the third angle:
[tex]\[ 180° - 77° = 103° \][/tex]
Therefore, the measure of the third angle in the triangle is:
○ A. 103°
