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

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
