1. The angles form a straight angle
2. A straight angle is defined to be 180 degrees
3. The three angles of any triangle always add to 180, as the diagram shows.
4. This is false. We need to add the three different angles A,B,C to get 180. Adding angle A to itself may not lead to 180. A+A = 180 only happens when angle A is a right angle (90 degree angle).
<span>You may deduce what it represents by analyzing the formula you just wrote.
Well, </span>the coefficient of linear expansion as the fractional change in length per degree of temperature change.
ΔL = c x L(initial) x ΔT
where c is the coefficient of linear expansion. You can rewrite the equation to give you c.
c = ΔL / [L(initial) x ΔT]
<span>Just substitute the variables and the answer will be
c = 0.000028. </span>
Now, what it represents.It may represent the extent to which the rod expands with temperature when compared to its original length.
Answer:
positive
