A sealed jar whose volume is exactly 1L which contains 1 mole of air at temperature 20-degree Celsius, assuming that the air behaves as an ideal gas. So what is the pressure inside the jar in Pa? (given:R= 8.314LkPa/molK)

What are the measures of ∠a, ∠b, ∠c and ∠d? explain how to find each of the angles. measure need asap

Which of the following is the true for f(x) = 5cos

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
