Think these are the answers to the first few hope it helps
X = 650 + 60t
The cheetah must arrive at the same place at the same time:
x = 90t
650 + 60t = 90t
30t = 650
t = 650/30 ≅ 21.7 s
It takes the cheetah a little more than 20 s running at 90 ft/s to reach the moving antelope, so assuming the antelope can maintain its speed of 60, it is safe.
Answer: In a rhombus, the opposite angles are congruent, and the adjacent angles are supplementary.
So, no matter how the figure is labeled, it is not a rhombus.
The sum of the interior angles of a quadrilateral is 360°.
The answer is obviously three.
