If you represent the problem in a diagram, you will form a triangle with 3 known length of the sides. When you are given all sides, and you are asked to find an angle, you can use the cosine law.
b^2 = a^2 + c^2 - 2ac*cosB
1.4^2 = 1.9^2 + 1^2 - 2(1.9*1)(cosB)
B = 45.78°
Let the length of one leg be x then another leg is (x+2)
According to Pythagoras theorem,
x^2 + (x+2)^2=16^2
=> x^2 + 2x - 126 =0
=>x= √(126 - 1) = 10.225
