select one:
a. c ≈ 25.1, a ≈ 26.8°, b ≈ 58.2°
b. c ≈ 25.1, a ≈ 22.8°, b ≈ 62.2°
c. c ≈ 25.9, a ≈ 22.8°, b ≈ 62.2°
d. c ≈ 25.9, a ≈ 59.2°, b ≈ 25.8°

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).

Complete the equation of the line through (−10,3) and (−8,−8). use exact numbers.
