Answer:
The original angle measures .
Step-by-step explanation:
We are asked to find the measure of original angle, when a ray divides an it into two complementary angles.
We know that two complementary angles add up-to 90 degree.
Therefore, the original angle is a right angle or the measure of original angle is .

Answer:
The answer to your question is 90 dB
Step-by-step explanation:
Data
I = 10⁻³
I⁰ = 10⁻¹²
Formula
Loudness = 10log ()
Process
1.- To solve this problem, just substitute the values in the equation and do the operations.
2.- Substitution
Loudness = 10 log
3.- Simplify
Loudness = 10log (1 x 10⁹)
Loudness = 10(9)
Loudness = 90
