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, given that the triangle has an obtuse angle at C and that a = 1, b = 9 and sin γ = 58.
calculate c =?
