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.
The dot product of vectors says , where
and
.
Given this, the dot product for these two vectors can be solved:
Our answer is 1, or choice C.
