Supplementary angles will always add up to 180. If you had a straight line, and you drew another line across that line, the two angles on either side of that line would add up to 180 because a flat line is equal to 180 degrees.
Answer:
-2.15
Step-by-step explanation: <em>I was kind of confused on what you asked. If you were asking for </em>0.4-2.55<em>, then that is the answer above.</em>
You have the formula already, just plug in 30 for s (speed) and solve for d (distance).
It all depends on the importance of the variable its self. Its important to solve it so you know what the variable is and its important to solve one at a time because its impossible to solve a variable completely if you have two of them
The answer is falseeeeeeeee
