a) The triangle △ ABC is right-angled with right angle at corner
C and angle α at corner A. Calculate a = | BC |, given that c = |
AB | = 8, and that tan α = 12.
Calculate a= ?
b) In the triangle △ ABC before the designations a = | BC |, b =
| CA |, c = | AB |, and ∠A = α, ∠B = β and ∠C = γ.
Find c,...
