Giving if you actually checked and didn't guess is this correct? responding due to annoying bots.

Yep, they are all correct

Step-by-step explanation:

I have not seen your previous post but am assuming you want me to check

1. Number one is correct, when we simplify the both of them, they are correct pr the same value. 1.5 = 1.5

2. Number two is also correct 38=38

3. And number three is also correct 2.4 = 2.4

All in all, all of them are correct, good job :)

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
