Answer:
Adjacent angles
complementary angles
Step-by-step explanation:
Adjacent angles are two angles that have a common side and a common vertex (corner point) but do not overlap in any way. When you break down the phrase adjacent angles, it becomes easy to visualise exactly what it is; they are two angles that are next to each other.
If the measure of two angles add up to 90 degrees the angles are called "complementary angles". For example, A = 30. o. and B = 60.
Let c represent the total time during which commercials appeared.
Then 3c+7 = program time = 30 minutes total
Then 3c = 23 minutes, and c = 7 2/3 minutes. This is close to 7.7.
