a=180-122=58°

Diameter always make angle 90° on the circumference.

so b=90°

∠B=1/2×58=29°

29+b+c=180

29+90+c=180

c=180-119=61°

First you need to multiply the number on the outside of the parentheses to what's inside. Then you need to subtract 1440 from both sides. After that you need to get all of the u's on one side so you subtract 256u from -160u and then you divide 832 by 96.
