If you're going to use technology (Brainly), you may as well use appropriate technology (a triangle solver). Many graphing calculators have this function built in.
a ≈ 5.82
A ≈ 21.2°
C ≈ 21.8°
Since the longest side (b) is opposite the given angle (B), the triangle has one solution.
.. C = arcsin(6/11*sin(137°))
.. A = 180° -137° -C
.. a = sin(A)*11/sin(137°)
