Answer:
120
Step-by-step explanation:
The sum of the angles is 180 since it forms a straight line
2x+ x+90 = 180
Combine like terms
3x +90=180
Subtract 90 from each side
3x+90-90=180-90
3x= 90
Divide each side by 3
3x/3 = 90/3
x = 30
We want angle DBC = x+90
= 30+90
=120
The correct answers are the Adriatic Sea, the Ionian Sea, the Ligurian Sea, and the Tyrrhenian Sea. Hope this helps.
Z would mean 0 considering they would both be the last
Answer:
x= -1
Step-by-step explanation
First move the variables to the left and change it's sign
(-6+x-2x=-5)
Then combine like terms
(-6-x=-5)
Then move the -6 to the right and combine it with the -5
(-x=-5+6)
(-x=1)
Lastly change the signs by dividing by 1
(x=-1)
