Answer:
25°
Step-by-step explanation:
A supplementary angle refers to two angles that measure up to 180° degrees when added together.
Let x = one of the angles
Let y = 115°
x = 65°
To find the complementary angle;
A complementary angle refers to two angles that measure up to 90° degrees when added together.
Let a = one of the angles.
Let b = 65°
a = 25°
<em>Therefore, the complement of an angle whose supplement is 115 degrees is 25 degrees. </em>
