Answer:
1.08 × 10^11
Step-by-step explanation:
Subtract: (1.8*10^11)-(7.2*10^10)
The square root of 2 is 1.41
A)
8^2+9^2=c^264+81=c^2
c^2=145c=sqrt 145c=12.04
B)
Pythagerean Theorum:
A^2+B^2=C^2, where C is the hypotenuse and A and B are the other legs
15^2=9^2+B^2
225=81+B^2
225-81=B^2
144=B^2 (square root both sides)
12=B
