Answer:
angles opposite each other are the same
this is called corresponding angles
Step-by-step explanation:
Answer:
Delta = |a b d; b c f; d f g|
(2)
J = |a b; b c|
(3)
I = a+c
(4)
K = |a d; d g|+|c f; f g|.
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
Used a scientific calculator.
Log(7x+1) - log(x-2) =1
log[(7x+1) / (x-2)] =1 or log[(7x+1) / (x-2)] =log10 (log10=1)
it means (7x+1) / (x-2) =10
Solving ===> x=7
