Answer:
A=47 Degrees
Step-by-step explanation:
all triangles add up to 180 degrees
exterior angles add up to 180
360-100+127
360-227
133=B
180-133=47
A=47 Degrees

Mean= 31
Step-by-step explanation:
To find the mean you need to add all the number together and then divide by how many ever numbers there are.

There are 5 numbers so you would divide by 5
155/5
=31
