Let, x,2x,3x,5x,9x be the angles of the pentagon.
Now, x+2x+3x+5x+9x= 540
$20x = 540 \\ x = 27$
So, smallest angle is 27.

A brass boiler has a base area of 0.15 m2 and thickness 1.0 cm. It boils water at the rate of 6.0 kg/min when placed on a gas stove. Estimate the temperature of the part of the flame in contact with the boiler. Thermal conductivity of brass = 109 J s –1 m–1 K–1; Heat of vaporisation of water = 2256 × 103 J kg–1.
