a. a=117 ft, b=16.35 ft  Applying the Pythagorean Theorem  a^2 + b^2 = c^2
  117^2 + 16.35^2 = c^2
 c = {{{sqrt(13689 + 267.32) = highlight(118.14)}}}
b. &#8736;B = 8° 29' OR (57°24' = (8° + 29/60)° = 8.4833° and a =  32.8 ft 
  cos(8.4833°) = adj/hyp = 32.8 /c
    c = 32.8/cos(8.4833°) = 33.16
May find a if You wish by Applying the Pythagorean Theorem
 {{{a = sqrt(33.15^2 - 32.8^2)}}}
Calculator makes short work of finding a
