The triangle above is changed so that the exterior angle shown measures 128 how does this affect angles b and c
2 answers:
There isn't enough information for me to help you. Could you attach a picture so that I can see the triangle and where angles B and C are? Thank you.
Answer:
the sum of the measures of angle B and angle C will also be 128 degrees meaning that the sum will decrease by 24 degrees.

Answer:
56.44 degrees
Step-by-step explanation:
sin(measure of the angle)=10/12
sin^-1(sin(measure of the angle))=sin^-1(10/12)
measure of the angle=56.44
