Answer:
24
Step-by-step explanation:
use Pythagoras theorem
a^2 + b^2 = c^2
18^2+b^2=30^2
b^2 = 30^2 - 18^2
b = √576 =24
Answer:
6
Step-by-step explanation:
The orange line doesn't pass 6, it stays at 6.
We can solve this in many ways, let's try this one.
T∧2 = 4 pi∧2 * a∧3 / GM First we will multiply whole equation with variable( or parameter) M and get
M * T∧2 = 4 pi∧2 * a∧3 / G After that we will divide whole equation with variable ( or parameter ) T∧2 and get
M = 4 pi∧2 * a∧3 / G * T∧2
This is correct answer
Good luck!!!
