Answer 1

Answer:

let the angle of triangle be A,B,C

A+B +C =180----------1

also A,B,C are in ap

so A+C =2B -----------2

substituting A+C =2B in equation 1

3B =180

B = 60° 60×π/180 rad = π/3rad

Answer 2

Explanation:

• For gaseous pollutants such as O3, NO2, and SO2, the site of deposition in the respiratory tract is largely a function of water solubility. For highly soluble gases, the nose serves an important defensive function because the air inhaled transnasally is passed over the large, irregular surface of the turbinates. The promotion of turbulent flow prolongs contact with the mucosal surface, increasing adsorption. Under conditions of quiet breathing, when most air is inspired transnasally, the concentration of SO2 that reaches the glottis is less than 2% of the concentration inspired at the nose
