Answer: C is 160 and B is 20

This is because they’re vertically perpendicular lines and we know that angles opposite each other equal the same. So the opposite B is 20 so b will also be 20 and to work out c you do 360-40= 320 and then you divide 320/2=
160

Hope this helps

Anna11 [10]

Answer:

Yes, there are infinite triangles with the same three angles but different side lengths

Step-by-step explanation:
