Can I have help?
Thank you

Read through the complete process and FOLLOW MY STEPS.

Step 1: Identify key details

UW is the diameter of the circle; it's a straight line.

TV is the radius, bisecting straight angle (180°) UTW, thus making angles UTV and VTW.

The measure of angle UTV is 111°.

Step 2: Find information by using Statement-Reason method

Statement: Reason

UTV + VTW = 180°: Supplementary angles

UTV = 111°: Given

VTW = 180° - 111° = 69°: Algebra

Hence, measure of angle VTW is 69°.

m∠VTW = 69°

Please rate, give feedback on how well I did, and criticize on what I can do better next time.

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p

(by the way, do you mind marking me as brainliest? i'd greatly appreciate it! mahalo! x3)
