FT = -(60°12/14.5//). In the right triangle RVM, RVM=RVT + TVM = 23° 27-(60° 1214.6)= -(36° 4514.5). By [39], sin RM = sin VMsin RVM. log sin Of = 9.95208 log sin R VM = 9.77698 log sin RM= 9.72906 RM = d = 32° 24 12. Also, by [42], sin VR = tan Elf cot RVM. log tan RM =9.80257log cot RVM = 0.12677… … Given c = 90° - 44° 50= 45° 10,A = 1386 58,B = 20°.i(A-B) = 59° 29.i (A + B) = 79° 29.ic = 22°35/.log cos i (A -B) = 9.70568log sec £(.4 + B) = 0.73869log tan | c = 9.61901log tan i(a + b) = 0.06338 f(a + &) = 49°9/57.7 log sin \ (A - B) = 9.93525 log esc $ (A + B) = 0.00736 log tan \ c =…
