Use the law of sines to find what angle r is:

= 75.9

Explanation:

From the Law of Sines

Sin A/a = Sin B/b = Sin C/c

Therefore;

Sin R/r = Sin S/s

Sine R/32 = Sin 52/26

Thus;

Sin R = (sin 52 × 32)/26

         = 0.96986

R = sin^-10.96986

R = 75.897

  = 75.9

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong
