Answer:
The answer is B.180°.
Step-by-step explanation:
The figure is rotationally symmetric is after a rotation of a given angle, it still look the same.
In this case of a rectangle, the only way to rotate it so that is look the same, is by rotating it by multiple of 180°, so that the up and down sides flip over, as well as the right and left sides.
Therefore, the only option that applies is B.180°
Step One
Figure out the actual change.
Change = 2.78 - 2.45
Change = 0.33
Step 2
Find the % change
% Change = 0.33/2.45 * 100 = 13.5%
Answer:
59
Step-by-step explanation:
F = 1.8c + 32
F = 1.8(15) + 32
F = 27+32
F = 59
Answer:
x = 4
Step-by-step explanation:
2x = 4x - 8
<em>subtract 2x from both sides of the equation</em>
2x - 2x = 4x - 2x - 8
0 = 2x - 8
<em>add 8 to both sides of the equation</em>
0 + 8 = 2x - 8 + 8
8 = 2x
<em>divide both sides of the equation by 2</em>
8/2 = 2x/2
4 = x
