Answer:
sorry don't play video games
Step-by-step explanation:
Its just pythagorean theorem so you would do this:
a^2+b^2=c^2
30^2+ 13^2= 1069
then u square root the answer (1069)
which would then give you 32.695
and then you round to nearest tenth which is one place after the decimal
32.7 would be your answer for the first one.
Hope that helps!
