The question has unclear information.
So, I'll answer from scratch
Given
ABC = Right angled triangle
DB bisects ABC
Required
Prove that CBD = 45
From the question, we have that:
ABC is right angled at B
So, when DB bisects ABC, it means that DB divides ABC into two equal angles.
i.e.

and

Substitute CBD for ABD in 


Divide both sides by 2



Hence, it is proved that

Answer:
C. The afternoon temperature was 6 degrees above the night temperature.
Step-by-step explanation:
this is correct because the 6 is 6 more than 0.
Step-by-step explanation:
n = 0
because,
p^0 = 1
10000000^0 = 1
A relation is a function if the value in its Domain does not occur more than once. This means each domain value is paired with exactly one value of range.
In the given scenario, the domain is the students (e.g name of a student) and the function returns the date of birth of the student. A student can have only one date of birth. So it is not possible that a value in Domain(i.e. a student) is paired with more than one date of births.
Therefore, we can conclude that the given relation describes a function.
