Step-by-step explanation:
Given:

Using formula:
For point a:

For point b:

For point c:

For point d:
Hence, the correct choice is "i".
For point e:

AC is not the bisector of angle BAD. AC made both sides a triangle and every triangles angles have to add to 180 degrees. So 115+30= 145 meaning angle DAC is 35 degrees. So AC cuts through BAD but one side is 30 degrees and the other is 35(DCB and DAB are the same angle…they both have to add up to 65 degrees)
Answer:
The sound intensity is about 101.9 dB
Step-by-step explanation:
Sound intensity is the amount of sound energy per unit area.
The intensity of the dog bark is 10⁻⁵ W/in². The intensity of sound in decibels is given by:

I = 10⁻⁵ W/in² = 0.0155 W/m²
Therefore:

The sound intensity is about 101.9 dB
Neagtive means go backwards or oposite
it takes away that many units
